What happens when sensible heat is added to a substance?

• A. It causes a change in state from solid to liquid.
• B. It cannot be detected by a thermometer.
• C. It causes a rise in temperature.
• D. It is the sum of latent heat and heat of evaporation.

Answer: (C)

When sensible heat is added to a substance, it causes a rise in temperature. Sensible heat refers to the heat that, when added to a substance, results in an increase in its temperature while the substance remains in the same phase (solid, liquid, or gas). This increase in temperature can be measured with a thermometer, which is an essential feature of sensible heat. The concept of sensible heat is distinct from latent heat, which is involved in phase changes (such as melting or boiling) where temperature remains constant despite the addition of heat. Therefore, upon adding sensible heat, the temperature of the substance increases, providing a clear and measurable effect.
