Answers

Answer: atmosphere

Explanation:

The atmosphere is the gaseous layer of the earth. It consists of mass of gaseous which are collectively called as air. In the air the particles such as dust particles, smoke, soot and chemicals are present. These are attracted by the gravitational pull of the planet. The atmosphere protects the earth from the entry of harmful UV and infrared radiations coming directly from the sun. This way atmosphere protects the living beings from damage caused by these radiations.

On the basis of the above description, atmosphere should be the focus of study.

It would be halved.
It would stay the same.
It would slightly decrease.

Answers

The pressure would increase. This can be explained by the ideal gas law where for an ideal gas its pressure, volume and temperature is a function of each other ans is expressed by an equation: PV = nRT. We first need to assume that this gas given is ideal. When the temperature and the number of moles is set to a constant value while the volume decreases, we can see that from the equation pressure and volume are indirectly proportional to each other, therefore as the volume decreases, the pressure inside increases.

Answer:

It would increase
