Which step will decrease the pressure of a gas inside a closed cubical container

Decreasing the temperature will decrease the pressure of a gas inside a closed cubical container. In a closed container, the Volume (V) is fixed and the no of mole of the gas(n) are also fixed. So, we write the gas equation : PV = nRT Here, V,R and n are constants. So, Pressure is directly proportional to the temperature. Thus, on increasing the temperature, pressure will increase and on decreasing the temperature, the pressure will decrease.

The answer is true for your question.
