Problem: The temperature of a piece of lead is increased from 20C to 35C while its volume is held constant by increasing the hydrostatic pressure. If the initial pressure is 1atm, what is the final pressure? Honestly, I'm not sure where to begin here. Everything we have done thus far has been in relation to gases and this isn't an ideal gas here. I know if a volume is constant it is considered a isochoric process and the process does no pressure-volume work. Also, Q=mCvΔT. But I am not sure where to go from here, much less how to relate this to a process involving a solid. Any help is much appreciated!
