What is Sensible Heat?

Sensible heat refers to the heat exchanged by a substance that results in a change in temperature without affecting its state. This means that when sensible heat is added or removed from a substance, you will observe an increase or decrease in temperature, while the substance remains in the same physical state—such as solid, liquid, or gas.

For example, when you heat water on a stove, it becomes hotter, but it remains in a liquid state as long as no boiling occurs. This aligns perfectly with the definition of sensible heat.

In contrast, the other options describe different phenomena. For example, the second option refers to heat transfer that results in both a change in temperature and a change in state, which is indicative of latent heat rather than sensible heat. The third option highlights heat that leads to a change in state without a change in temperature, again pointing to latent heat. Lastly, the fourth option describes a scenario where neither temperature nor state changes, which does not pertain to any heat transfer scenario relevant to this context.
