Question

A container holds $1$ mole of an ideal gas. If the temperature of the gas is held constant and the volume of the gas is halved, the pressure of the gas will double. This happens because

• A. The gas particles have gained energy
• B. The gas particles collide with one another more often
• C. The gas particles move more slowly
• D. The gas particles collide with the container walls less often
• E. The gas particles collide with the container walls more often

Answer 1

The correct option is E The gas particles collide with the container walls more often

When the volume of gas is halved , gas molecules get less space to move , hence gas particles collide with the wall of container more often and thus transfer more momentum to walls which increases the pressure of gas.
