Physics
1 answer:
Lesechka [4]2 years ago
5 0

Explanation:

Heat liberated by a body depends on the mass of the body, the specific heat capacity of that body and the change in temperature experienced by the body.

Heat energy by a body depends on the surface area of the body A as well as the temperature of body T.

According to Stefan's law, rate of heat energy radiated by a body is given by P=σAeT^4

Thus more is the temperature of body, more is the heat radiated. Also mores is the surface area of body, more is the heat radiated.

We (earth) belong to the Milky Way galaxy, our galaxy got this name from the Romans.
