One half mole of ideal gas is taken front state a to state c. (a go down to b and b to c in a line) a pressure is 4.0x10^5, V is .002m^3, b pressure is 2.0x10^5, V is .003m^3 and c pressure is 2.0x10^5 V is .004m^3.
A) Calculate the final tempperature of the gas
B) Calculate the work done on (or by) the gas as it moves from state a to state c
C) Does heat leave the system or enter the system during the process? How muich heat? explain.
