Heat 4

HEAT-4 Problem 98 A mono atomic gas initially at the temperature T = 25 and pressure of 2 atmospheres is expanded to a final pressure of 1.0 atmosphere. a) Isothermally and reversibly b) Isothermally against a constant pressure of 1.0 atmosphere. Calculate for each case: (i) The final temperature of the gas (ii) The increase of internal energy Problem 99 The figure below shows some details concerning the behavior of a fixed mass of a gas assumed to be an ideal one in a petrol engine. The gas starts at A with a volume 5 , temperature 300 K and a pressure of 1 . In the change from A to B it is compressed to volume of 1 , the pressure rises to 1.5 . And temperature 630K
