Molar Heat Capacity

Postby Crystal Escobar 1F » Fri Jan 08, 2016 9:17 pm

Can the equation to find the heat required, (qp)=∆H=nCp∆T, still be used with a value for constant volume instead of pressure?

It can be ONLY in the case of LIQUID or SOLID. The reason is that the volume barely changes with pressure. It is not true anymore for gas since the volume can hugely change with a change in pressure.
