During isothermal expansion at 800 K, the working substance of a Carnot's engine extracts 480 cal of heat. If the sink be at 300 K, calculate (i) the work done by the working substance during isothermal expansion (ii) the work done on the substance during isothermal compression (iii) the efficiency of the ideal engine.
