If you decreased the volume of a sample of gas by a factor of three while maintaining a constant pressure, how would the absolute temperature of the gas be affected? 1. It would remain the same 2. It would decrease 3. It would increase threefold

correct option: 2 -> It would decrease.

Step-by-step explanation:

If the amount of gas is the same, the following relation needs to be constant:

So, If the pressure is constant, the volume and the temperature are directly proportional (if one increases, the other also increases).

Then, an decrease of 3 times in the volume would cause an decrease of 3 times in the temperature.

So the correct option is 2.: It would decrease.
