##### Reference no: EM13708893

A piston cylinder closed system expands from state 1 to state 2 due to heat addition and then is compressed from state 2 to state 3. If this process (1-2-3) is a cycle, what can be said about Temperature (T) and Pressure (P)?

a. T1 > T3, and P1=P3

b. T1 < T3, and P1=P3

c. T1 = T3, and P1>P3

d. T1 = T3, and P1=P3

e. T1 = T3, and P1
