Answer: Option (b) is the correct answer.
Explanation:
Heat is defined as the energy obtained by the molecules of an object that travels from a hotter body to a colder body.
For example, a metal spoon placed in a cup full of hot tea. Then transfer of heat will take place from the tea to the spoon.
And, this transfer of heat will continue till the temperature of both the objects become equal.
Thus, we can conclude that heat is the energy that moves from a hotter object to a colder object.
