A sample of gas observe 4000 kilo joule of heat question number if volume remains constant what is a delta u question number B suppose that in addition to absorption of heat by the simple the surrounding does 2000 kilo joule of work on the sample, what is delta U A sample of gas absorbs 4000 kJ of heat. (a) If volume remains constant, what is AU? (b) Suppose that in addition to absorption of heat by the sample, the surroundings does 2000 kJ Of work on the sample, what is AU? "c) Suppose that as the original sample absorbs heat, it expands against atmospheric pressure and does 600 kJ of work on its surroundings. What is AU? 4000 kJ (b) 6000 kJ (c) 3400 kJ1
