Explain why higher temperature in a substance does not mean the substance has more thermal energy?

Answers

Answer 1

Answer:

Temperature is the average kinetic energy of particles of an object. Warmer objects have faster particles and higher temperatures.

Explanation:

If two objects have the same mass, the object with the higher temperature has greater thermal energy. Temperature is measured with a thermometer.

The four options that accurately describe reproduction in gymnosperms are:Fertilized ovules grow into seeds.Male and female cones may grow on the same plant.Most gymnosperms produce male and female cones.Some require heat for seed dispersal.Female cones do not produce pollen in gymnosperms. Instead, male cones produce pollen which is then carried by the wind or insects to the female cones for fertilization.

How is energy involved in physical change?

Answers

the amount of energy that is used changes the amount of physical change that is shown

During phase changes, energy changes are usually involved. For example, when solid dry ice vaporizes (physical change), carbon dioxide molecules absorb energy. When liquid water becomes ice, energy is released. Remember that all chemical reactions involve a change in the bonds of the reactants.

How is the stimulus concept currently in our lives? (Ivan Pavlov) in TTQA

Answers

Answer:

stimulus is anything that can trigger a physical or behavioral change. The plural of stimulus is stimuli. Stimuli can be external or internal. An example of external stimuli is your body responding to a medicine. An example of internal stimuli is your vital signs changing due to a change in the body.

As humans, we detect and respond to stimulus in order to survive. For example, if you walk outside on a very sunny day, your pupils will constrict to protect your eye from taking in too much light and being damaged. Your body reacts to the stimulus (the light) to protect you.

How did this piece of evidence change your thinking about the channel on Mars? Explain your ideas below.

How did this piece of evidence change your thinking about the channel on Mars? Explain your ideas below.

Answers

The piece of evidence changed thinking about the channel on Mars because it shows that the rock was formed next to flowing water as such rock formations exist on Earth and were formed by flowing water.

Was there flowing water on Mars ?

The geologic process that could have created the channel on Mars is water moving. We can infer from the image that water running across the terrain on Mars created channels similar to those on Earth.

We can claim that the flowing of water creates the channels on Mars because when the water runs for a long period from the same region, it takes the sediments and creates channels.

How do you think heat moves through Earth's atmosphere?

Answers

Answer:

Conduction, radiation and convection all play a role in moving heat between Earth's surface and the atmosphere. Since air is a poor conductor, most energy transfer by conduction occurs right near Earth's surface. Conduction directly affects air temperature only a few centimeters into the atmosphere.

How does most ocean water return to the ocean in the water cycle?

Through precipitation over the ocean
By flowing through rivers and streams
Through runoff on Earth's surface
By wind blowing water back to the ocean

Technique B: Used a genetically modified variety of corn. The plant produces an insecticide which selectively kills only the moth larvae as it feeds on the corn.

Which technique is likely to have less of an impact on the environment?

Technique B because it may help humans who consume corn to fight bacteria
Technique A because it kills a broader variety of insects to protect the corn
Technique B because it preserves the harmless insects and targets only the moth larvae
Technique A because insecticide use is better for preserving the environment.
