What is the best coefficient of performance for a refrigerator that cools an environment at -R, °C and
has heat transfer to reservoir at 150.0°C? (b) How much work in joules must be done for a heat transfer of
4186 kJ from the cold environment? (c) What is the cost of doing this if the work costs 0.1 Rs per 3.60 ×
10° J (a kilowatt-hour)? (d) How many kJ of heat transfer occurs into the warm environment?
where, R, is last two digits of registration no. (e.g. for registration no. 11603309 take R¡ as 9 °C
