One-half mole of an ideal gas is taken from state a to state c as shown in ?Fig. P19.34?. (a) Calculate the final temperature 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 this process? How much heat? Explain.

Solution 40P Step 1: The expression for an ideal gas equation is PV = nRT Here P is pressure,V is volume,n is number of moles of gas,R is gas constant and T is temperature. Step 2: (a).The final temperature of gas T f P V fnRf 5 T f (4.0 × 10 )(0.004)/1/2(8.314) T = 384.89 K f
