Answer the following statement true (T) or false (F)
Two moles of helium, which you can model as an ideal gas with Cv*= (3/2)R, is confined in a rigid vessel (constant volume) that is sealed and has no interior moving parts. Initially, the gas has P=1 atm and T=300 K. If 1000 Joules of heat are added to the vessel, determine:
A) The amount of work added to, or removed from, the helium. B) The final temperature of the helium. C) The change in entropy of the helium. (If you have no answer to part B, assume the final temperature is T=400 K).
