What type of heat causes temperature changes without altering the state of a substance?

The correct answer is "sensible" heat. Sensible heat refers to the energy added or removed from a substance that results in a change in temperature, but does not cause a phase transition, meaning the state of the substance remains unchanged. This type of heat is experienced when a substance is heated or cooled while remaining in the same physical state, for example, heating water from 20°C to 80°C will increase its temperature without changing its state from liquid to vapor.

In contrast, latent heat is the energy required for a substance to change from one phase to another (for example, melting ice to water or water to steam) at a constant temperature. This type of heat does not cause a temperature change, as the energy is being used to overcome the forces holding the molecules together, rather than increasing their kinetic energy.

Superheat and specific heat are terms that relate to different aspects of heat transfer. Superheat refers to the process of heating a vapor above its boiling point without it condensing, and specific heat is a measure of the amount of heat required to change the temperature of a unit mass of a substance by one degree Celsius. Neither of these options accurately describes the concept of heat that leads to temperature changes without altering the state of a
