Set 2: (50 pts) Consider 1.0 mole of a monotomic ideal gas (system) which is initially equilibrated at a temperature of 500 K in a container with a volume of 1 m, and then undergoes a reversible isothermal expansion to a volume of 2 m'. 1. (10 pts) What is the internal energy (U) of the gas (in Junits)? 2. (10 pts) What is the internal energy change (AU) of the gas (in J units)? 3....
Difference in final temperatures? Please show all steps
Two containers (call them A and B) with the same initial volume, V 31 L, hold the same amount of monatomic ideal gas, say helium, at the same initial temperature T = 301 K and the same initial pressure Pi 1 atm. Container A holds the gas at a constant volume and Container B holds the gas at a constant pressure If you add Q 5389 J of heat to both containers,...
