What is defined as heat that causes a change in temperature of a substance?

Sensible heat is specifically defined as the heat that leads to a change in temperature of a substance without changing its phase. When sensible heat is added to or removed from a substance, its temperature increases or decreases accordingly. This is a fundamental concept in thermal physics and HVAC applications, as it relates to how temperatures of various substances, including air and refrigerants, respond to heat transfer.

In the context of HVAC, understanding sensible heat is crucial for effectively managing indoor temperatures and ensuring comfort in heating and cooling systems. For example, when warm air is blown into a room, it raises the temperature of the air particles, which is a direct result of sensible heat.

Latent heat, on the other hand, refers to the heat energy associated with phase changes, such as the transition of water from ice to steam, without a change in temperature. Superheat is a state in vapor compression refrigeration where the refrigerant vapor is heated beyond its boiling point, also without a temperature increase due to pressure considerations. Regular heat as a term does not have a specific definition in thermodynamics or HVAC, making it less relevant in this context. Therefore, sensible heat is clearly the definition that fits the requirement of causing a change in temperature specifically.
