Question

If a mass of gas is confined in a closed container with a movable piston above the gas and a small downward force is applied to the piston, the volume of the gas will be

a. reduced slightly.
b. increased slightly.
c. increased considerably.
d. reduced considerably.

Answer 1

I believe its a trick question.
I think option D is the right answer.
If the piston pressurises the gas in a tight container the gas should reduce.
and to pick between A and D, D seems correct as the piston continuously moves.
