A cylinder contains an ideal gas with temperature $293\text{ K}$ and absolute pressure $101{,}000\text{ Pa}$. The cylinder is then placed in contact with very a cold reservoir, which conducts energy away from the gas. The gas is held at constant volume. After some time the pressure in the gas is $92{,}000\text{ Pa}$.

Which additional quantities must be measured in order to determine the amount of heat that was removed from the gas?

Select TWO answers.


The number of moles of gas in the cylinder.


The volume of the cylinder.


The temperature of the cold reservoir.


The time that passes between pressure measurements.
