## Question:

Given a body at 50 degrees C with a surface area of 0.15 meters squared and an emissivity of 0.7, calculate the rate of radiant energy leaving the body.

It is the process of exchange of heat from a body to space. The transferred heat varies according to the temperature, area and emissivity of the body. This process can also occur in the absence of any medium.
