If a gas has a pressure of 1.69 atm at a temperature of 300 K, what will the pressure change to if the container is cooled to 100 K?
Also
If a gas has a pressure of 715 mm Hg at the temperature of 500 K, what will the pressure change to if the container is heated to 900 K?
Answers
Answer:
The First one is: 0.563atm
The second one is: 1.692atm
Hope this helps!
Explanation: Look at Photo Attached
The pressure has been reduced with the cooling of the container, and the change in pressure has been 1.06 atm. The pressure has been increased with the heating of the container and the change in pressure has been 572 mm Hg.
Assuming the gas has been following the ideal behavior. According to the ideal gas equation,
PV =nRT
If the same gas has been heated, the n and R will be constant, as well as with the constant volume of initial and final pressure, the relationship to the P and T can be given as:
\(\rm \dfrac{Initial\;pressure}{Initial\;temperature}\;=\;\dfrac{Final\;pressure}{Final\;temperature}\)
(a) For the gas with an initial pressure of 1.69 atm, the final pressure will be:
\(\rm \dfrac{1.69}{300}\;=\;\dfrac{Final\;Pressure}{100}\)
Final pressure = 0.563 atm.
The change in pressure = Initial pressure - Final pressure
The change in pressure = 1.63 - 0.563 atm
The change in pressure = 1.06 atm.
The pressure has been reduced with the cooling of the container, and the change in pressure has been 1.06 atm.
(b) For the gas at initial pressure 715 mm Hg, the final pressure will be:
\(\rm \dfrac{715}{500}\;=\;\dfrac{Final\;Pressure}{900}\)
Final pressure = 1,287 mm Hg.
The change in pressure = Final pressure - Initial pressure
The change in pressure = 1,287 - 715 mm Hg
The change in pressure = 572 mm Hg
The pressure has been increased with the heating of the container and the change in pressure has been 572 mm Hg.

How is density different from weight and mass?
Answers
Hello there!
How is density different from weight and mass you say? It's simple!
1. Unlike weight, density is composed of mass and volume.
2. By dividing the mass over the volume, you can determine an object's density, while weight is the product of mass and gravity.
Hope this helps :) if so, can I get Brainliest?
Weight is how heavy an object is/ how much force it exerts
Mass is how much matter is in an object

Aside from the tasks it performs, perhaps the most important function of a circuit board is providing a way to integrate the electronics for a device in a compact space. A PCB allows components to be correctly connected to a power source while being safely insulated. Also, circuit boards are less expensive than other options because they can be designed with digital design tools and manufactured in high volume using factory automation.

Copper(II) chloride is the chemical compound with the chemical formula CuCl 2. This is a light brown solid, which slowly absorbs moisture to form a blue-green dihydrate.
Etching helps us to see the structure of the atoms of copper.
What is etching?The term etching refers to the process by which we expose the inner structure of copper. It is usually done electrically or by the use of an acid. The surface of the copper is removed and the inner structure of the copper is shown.
As such, when you etch copper, you can see the inner structure such as the arrangement of the atoms of copper and how they fit together.
As such looking through the etched copper would help you to appreciate that matter is composed of atoms.

How could the boy playing ping pong keep from hitting the ball off the table?

Answers
Answer: He needs to hit the ball with less force.
Explanation:
hope this helps
2. Based off the answer to the first question, by hitting the ping pong ball, momentum is transferred from the boy to the ball. Causing the ball to have more velocity/speed and gain more momentum.
3. Momentum before = momentum after
Every time the ball hits the table, some momentum transfers from the ball to the table. Every time the player hits the ball, some momentum transfers from the player to the ball. This allows the player to continue playing ping pong as the ball always has momentum.
2. Which of the following statements about inertia is correct?
A. The more mass a body has, the more inertia it has.
B. The more mass a body has, the less inertia it has.
C. The amount of inertia a body has is not dependent upon its mass.
D. An object has to be moving to have inertia.
Please use your brain only if you know, not google or anything else :)
Answers
Hope this helps :)
My number is- (856)449-5259
The statement that says the more mass a body has, the more inertia it has is correct about inertia (option A).
First, we need to recall the concept of inertia.
Inertia is the tendency of an object to oppose any change in its state. An object at rest will remain in this state until a force acts on it to move it, and vice versa, an object in motion will tend to keep the same velocity until a force acts on it to increase or slow down its speed.
Let's evaluate each statement
A. The more mass a body has, the more inertia it has.
It is true. The more body mass, the more tendency it will have to oppose the change in its state, so the force needed will be greater.
\( F = ma \)
We can see in the above equation that the force applied is proportional to the body mass.
B. The more mass a body has, the less inertia it has.
It is false. In statement A, we said that the more body mass, the more inertia it has.
C. The amount of inertia a body has is not dependent upon its mass.
It is false. According to the inertia concept, the inertia of a body is directly proportional to its mass.
D. An object has to be moving to have inertia.
It is false. As we said above, inertia is related to a body in a state of motion as well as in a state of rest.
Therefore, statement A is correct about inertia.

What we eat, and how we move our bodies, effects our blood. How does that end up affecting our other organs in the body
Answers
Answer:
The digestive system converts the foods we eat into their simplest forms, like glucose (sugars), amino acids (that make up protein) or fatty acids (that make up fats). The broken-down food is then absorbed into the bloodstream from the small intestine and the nutrients are carried to each cell in the body.
Answer:
The digestive system is made up of the gastrointestinal tract—also called the GI tract or digestive tract—and the liver, pancreas, and gallbladder. The GI tract is a series of hollow organs joined in a long, twisting tube from the mouth to the anus. The hollow organs that make up the GI tract are the mouth, esophagus, stomach, small intestine, large intestine, and anus. The liver, pancreas, and gallbladder are the solid organs of the digestive system.
The small intestine has three parts. The first part is called the duodenum. The jejunum is in the middle and the ileum is at the end. The large intestine includes the appendix, cecum, colon, and rectum. The appendix is a finger-shaped pouch attached to the cecum. The cecum is the first part of the large intestine. The colon is next. The rectum is the end of the large intestine.

Blake is using a screw to hang on a picture in his room. Which of the these is the best description of a screw?
A. A screw allows you to use less force because a screw acts like a pulley.
B. A screw allows you to use less force because a screw acts like an inclined plane.
C. A screw allows you to do less work because a screw acts like a pulley.
D. A screw allows you to do less work because a screw acts like an inclined plane.
Answers
When using a screw to hang a picture, it is important to understand its function. The best description of a screw is option B - "A screw allows you to use less force because a screw acts like an inclined plane."
Screws are simple machines that have an inclined plane wrapped around a cylinder. This inclined plane is known as the thread. As the screw is turned, the thread pulls the screw into the material it is being screwed into, allowing it to hold on tightly.
Because of this design, screws are able to reduce the amount of force needed to hold an object in place. This is because the force applied to the screw is spread out over a larger area, making it easier to turn the screw and insert it into the material.
In conclusion, when using a screw to hang a picture or any other object, remember that it is an inclined plane wrapped around a cylinder, designed to reduce the amount of force needed to hold an object in place.
Answer: The answer is B! <3
Explanation:
When Blake puts a screw into his wall, it is a good description of an inclined plane. The threads of a screw act like an inclined plane to increase the distance over which you exert the input force. As the threads of the screw turn, they exert an output force on the wood, pulling the screw into the wood. So the answer is B. I hope this helped! :)
