Increase in temperature of a gas filled in a container would lead to:

Question

G1 Physics · Accepted Answer

Step 1: Average translational kinetic energy per molecule is ⟨K⟩ = (3/2)kBT. Step 2: Hence average kinetic energy increases linearly with absolute temperature T. Step 3: Increasing T does not change the total mass of a sealed sample. In a rigid container the average pressure normally increases, not decreases. Final answer: (A).
