Understanding the Answer

Let's break down why this is correct

Answer

According to the Ideal Gas Law, \(PV = nRT\). If the temperature \(T\) stays the same and the pressure \(P\) goes up, the product \(PV\) must stay constant for a fixed amount of gas, so the volume \(V\) must shrink. Think of a balloon: squeezing it raises the pressure inside, so the balloon’s size (volume) becomes smaller. For example, if a gas at 1 atm pressure and 300 K is compressed to 2 atm while keeping 300 K, its volume will drop to half its original size. Thus, higher pressure at constant temperature leads to a smaller volume.

Detailed Explanation

When pressure goes up, the gas molecules squeeze tighter, so the space they occupy becomes smaller. Other options are incorrect because Some think higher pressure pushes gas out, making volume larger; People may believe volume stays the same if temperature is constant.
