What type of heat application results in a temperature change?

• A. Latent heat
• B. Specific heat
• C. Sensible heat
• D. Enthalpy

Answer: (C)

Sensible heat is the type of heat application that results in a temperature change in a substance. When energy is added to or removed from a system in the form of sensible heat, it directly affects the temperature of that system. For example, heating water in a pot will increase its temperature as you add heat; this is the result of sensible heat. The temperature change can be monitored using a thermometer, providing a clear and direct measurement of how much the temperature rises or falls as heat is added or removed. In contrast, latent heat refers to the heat required for a substance to change its phase (such as from solid to liquid or liquid to gas) without a temperature change occurring during the phase transition. Specific heat is a property that quantifies how much heat is needed to raise the temperature of a unit mass of a substance by one degree Celsius, but it does not in itself indicate a change. Enthalpy, on the other hand, is a more comprehensive thermodynamic concept that includes both sensible and latent heat but does not directly describe temperature change like sensible heat does.
