If the mass flow rate of the air at the initial state is 27.7 kg da/s , then the increase in the water content of the air is -0.039648 kg/s.

The process can be drawn on a psychrometric chart as shown below:

In order to solve the problem, the following steps are to be followed:

Step 1: Find the Humidity Ratio at state 1
The Humidity Ratio (ω1) can be found using the formula:

\(Relative Humidity (RH1) = (ω1/ωsat) × 100\)

Where,

ω1 = Humidity Ratio at State 1

ωsat = Saturation Humidity Ratio at State 1

The value of saturation humidity ratio (ωsat) can be obtained from the psychrometric chart.

ωsat at State 1 corresponds to temperature T1 and 100% relative humidity.

From the chart,ωsat = 0.012 kg water/kg dry air.

Therefore,

RH1 = (ω1/ωsat) × 100

80% = (ω1/0.012) × 100ω1

= (80/100) × 0.012

= 0.0096 kg water/kg dry air.

Step 2: Find the Humidity Ratio at state 2The Humidity Ratio (ω2) can be found using the formula:

RH2 = (ω2/ωsat2) × 100

From the chart,ωsat2 = 0.0136 kg water/kg dry air.

Therefore,

RH2 = (ω2/ωsat2) × 10060%

= (ω2/0.0136) × 100ω2

= (60/100) × 0.0136

= 0.00816 kg water/kg dry air.

Step 3: Find the increase in Humidity Ratio

Increase in Humidity Ratio \((Δω) = ω2 - ω1Δω\)

= 0.00816 - 0.0096

= -0.00144 kg water/kg dry air.

The negative sign indicates that there is a decrease in the water content of the air.

Step 4: Find the Mass flow rate of water

Mass flow rate of water can be found using the formula:

Mass flow rate of water = Mass flow rate of dry air x ΔωMass flow rate of water

= 27.7 x (-0.00144)

= -0.039648 kg/s.

Therefore, the increase in the water content of the air is -0.039648 kg/s.

The way that plate boundaries in Iceland and Chile similar is that both are  have volcanoes  and Earthquakes. The way that they are different is that Iceland  is  one that lies in the Mid-Atlantic Ridge while that of Chile is in the convergent plate boundary.

Iceland is situated on the Mid Atlantic Ridge, a divergent plate boundary where the Eurasian Plate and North American Plate are moving apart. Magma or molten rock rises to the surface and erupts as lava to form new ocean crust as the plates separate.

Two tectonic plates can diverge from one another, creating a border. As magma rises from the Earth's mantle to the surface and solidifies to form new oceanic crust, earthquakes frequently occur along these boundaries.

Chile is located on top of the South American tectonic plate, along with the other nations of the continent. The Nazca Plate joins the Pacific Plate at a divergent plate boundary known as the East Pacific Rise to the west of Chile. This region is beneath the Pacific Ocean.

Coral bleaching is a process where the coral lose their color and turn white, which makes them vulnerable and susceptible to disease.

Changes in ocean chemistry: The changes in ocean chemistry occur due to the increased absorption of carbon dioxide (CO2) by seawater. When CO2 mixes with seawater, it causes the water to become more acidic, leading to a reduction in the amount of carbonate ions, which is an essential component of the corals' calcium carbonate structures.

As a result, the coral reefs are weaker, and their resilience to other environmental stressors, such as coral bleaching, is reduced.

Warming waters: Coral reefs thrive in warm water conditions, and temperature changes can cause coral bleaching. When the ocean's temperature rises, the coral will lose their color and become more susceptible to disease.

Pollution: Human activities such as agriculture, industrialization, urbanization, and others lead to the release of various chemicals, fertilizers, pesticides, and plastics into the water. These pollutants can cause coral bleaching and also lead to death of corals.Rugosa Coral and Tabulata Coral are not potential stressors that could cause coral bleaching.

The UNFAO (United Nations Food and Agriculture Organization) has indeed demonstrated that forest loss has slowed down in recent years. However, this positive trend is still not enough to fully address the problem of deforestation and its negative impacts on the environment and society.

According to the latest Global Forest Resources Assessment (FRA) report released by the UNFAO in 2020, the world's total forest area was about 4.06 billion hectares, or 31% of the global land area. While this is a slight increase from the previous FRA report in 2015, which reported 4.01 billion hectares of forest cover, it is still significantly lower than the original baseline of 4.46 billion hectares in 1990.Moreover, the FRA report also reveals that the rate of forest loss has decreased over the past decade, from 7.8 million hectares per year in the 1990s to 4.7 million hectares per year between 2010 and 2020. This is largely due to various efforts and initiatives aimed at reducing deforestation and promoting sustainable forest management, such as forest conservation and restoration, certification schemes, and community-based forestry.Therefore, while the UNFAO's data shows that forest loss has slowed down, it is clear that more needs to be done to protect and restore the world's forests. This requires a multi-faceted approach that involves addressing the root causes of deforestation and promoting sustainable forest management, while also supporting the livelihoods and rights of local communities who depend on forests.
