Here's why:
* Temperature and Volume: The temperature of a gas is directly proportional to its volume. This means that as temperature decreases, the volume will also decrease.
* Pressure and Volume: The pressure of a gas is inversely proportional to its volume. This means that as pressure decreases, the volume will increase. However, in this scenario, the pressure is staying constant.
Think of it like this:
Imagine a balloon. If you cool the balloon down (lower the temperature), the air inside will contract, causing the balloon to shrink (decrease in volume).
Important Note: This relationship between temperature, pressure, and volume is described by the Combined Gas Law. It states that:
P₁V₁/T₁ = P₂V₂/T₂
Where:
* P = Pressure
* V = Volume
* T = Temperature (in Kelvin)
* The subscripts 1 and 2 represent the initial and final states of the gas.
