Which type of heat requires more energy to change, latent or sensible heat?

Latent heat requires more energy to change compared to sensible heat. This is because latent heat is involved in phase changes of a substance, such as melting, boiling, or sublimation, where energy is absorbed or released without a change in temperature. For instance, when ice melts to water, it absorbs a significant amount of energy in the form of latent heat, but the temperature remains constant until the entire phase transition is complete.

In contrast, sensible heat refers to the energy that causes a change in temperature of a substance without changing its phase. While both types of heat involve energy transfer, the energy associated with latent heat is substantially greater when it comes to changing the state of a material. This distinction highlights why latent heat is the correct choice, as it illustrates the greater energy requirement during phase transitions compared to temperature changes alone.
