A sample of an ideal gas in taken through the cyclic process abca in the given figure. It absorbs 50 J of heat during the parth ab, no heat during bc and rejects 70J of heat during ca, 40 J of work is done on the gas during the part bc. (a) Find the internal energy of the gas at b adn c if it is 1500 J at a. ltbr. (b) Calculate the work done by the gas during the part ca.

In figure, a sample of an ideal gas is taken through the cyclic process abca. 800J of work is done by the gas during process ab. If gas absorb no heat in process ab, rejects 100J of heat during bc and absord 500J of heat during process ca . Then (a) find the internal energy of the gas at b and c if its is 1000J at a (b). Also calculate the work by the gas during the part bc ,

A sample of an ideal gas is taken through the cyclic-process ABCA shown in Fig. It rejects 50 J of heat during the part AB , doens not absorb or reject the heat during BC , and accepts 70 J of heat during CA .
