3. Define the following terms:

(c) Radiant heat
(d) Conduction​

Answer 1

Radiant heat: It is the heat which is produced by radiation. In other words, it is the heat produced by any body and it depends upon the size of the body. The sun produces more radiation as its size is more and it's radiation is more. We too produce heat and that is the radiant heat of our body.

Conduction: It the the property of an object to allow heat to pass through it easily. These kind of substances are called conductors.

Answer 2
