Question

what do you mean by
"You can ignore the THERMAL CONTRACTION of the cylinder" ?? xD

Answer 1

the question is this.

Six moles of an ideal gas are in a cylinder fitted at one end with a movable piston. the gas is cooled until the pressure increases to 30% of its original value. you can ignore the thermal contraction of the cylinder.

Answer 2

n=6 moles
\[p_{2} = p_{1} (0.3+1)\]

Answer 3

I think that means to assume volume is constant.

Answer 4

so the change of volume is zero?
\[(V_{2} - V_{1}) = 0\]
