Answer: Option (a) is the correct answer.
Step-by-step explanation:
It is known that transfer of heat occurs from hot object to cold object when they are placed adjacent to each other. And this kind of transfer of heat is known as conduction.
For example, when cold hands are placed around or near a hot cup of coffee then transfer of heat takes place from hot cup to the cold hands.
Heat always transfers from hot object to cold object because the molecules of a hot object has more kinetic energy and therefore they release extra energy in the form of heat.
Thus, we can conclude that the situation where a hot cup of coffee transfers heat to cold hands is accurate regarding the transfer of heat.
