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