(adsbygoogle = window.adsbygoogle || []).push({}); 1. What is the value of Q in this problem? Is it a value that's stated in the question or does it need calculating?

A sample consisting of 5 moles of an ideal gas at a temperature of 300 K and a

pressure of 1.00 × 105 Pa is heated to a temperature of 500 K at constant pressure.

The amount of heat transferred to the gas is 29.1 kJ.

2. Relevant equations

No equations needed really, I just need to make sure I'm using the right values!

3. The attempt at a solution

Is Q = 29.1 kJ = 29100 J (or would that be U?)

Is Q the same value for constant volume and constant pressure while ΔU changes because ΔU = Q + W and there is no work in a constant volume situation?
