When a gas expands along AB, it does 500J of work and absorbs 250 J of heat. When the gas expands along AC, it does 700J of work and absorbs 300J of heat.

(a) How much heat does the gas exchange along Bc?
(b) When the gas makes the transition from C to A along CDA, 800J of work are done on it from C to D. How much heat does it exchange along CDA?

Find the magnitude of change in internal energy when system does 150J work and absorbs 200J heat

An ideal gas expands isothermally along AB and does 700J of work. How much heat does the gas exchange along AB? The gas then expands adiabarically along BC and does 400J of work. When the gas returns to A along CA, it exhausts 100J of heat to the surroundings. How much work is done on the gas along this path?

A heat engine absorbs 300J of heat at 627^(@)C and rejects a part of it at 27^(@)C . Find the work done by the engine.
