A biology laboratory is maintained at a constant temperature of 7.00°C by an air conditioner, which is vented to the air outside. On a typical hot summer day, the outside temperature is 27.0°C and the air-conditioning unit emits energy to the outside at a rate of 9.60 kW. Model the unit as having a coefficient of performance equal to 40% of the coefficient of performance of an ideal Carnot device.
