Problem 31P

A restaurant refrigerator has a coefficient of performance of 5.0. If the temperature in the kitchen outside the refrigerator is 29°C, what is the lowest temperature that could be obtained inside the refrigerator if it were ideal?

Step-by-Step Solution:

SolutionStep 1 of 4Intensity of EM wave emitted by sun is the energy transmitted per unit areaperpendicular to the direction of propagation per unit time.Since energy per unit time is given by power.The intensity can be defined as the power radiated per unit area perpendicular to thedirection of propagation.That is P I = AFrom the above equation, solving for Power, P = I AWhere I is the intensity, P is the power and A is the area.
