Sensible heat is heat that causes what kind of change in a substance?

• A. A change of state
• B. A change in temperature
• C. A change in pressure
• D. A change in color

Answer: (B)

Sensible heat refers to the heat absorbed or released by a substance when it undergoes a change in temperature without a change in state. When a substance is heated or cooled and experiences a temperature change, this heat energy is known as sensible heat. For example, warming up water from room temperature to its boiling point involves sensible heat, as the state of the water remains liquid throughout the temperature change. The other options relate to different types of heat transfer or changes in physical properties. A change of state involves latent heat, which is the heat energy required for a substance to change from one state to another, such as from liquid to gas, without a temperature change. A change in pressure typically pertains to thermodynamic processes and not directly to heat transfer in the context of sensible heat. A change in color can occur for various reasons, but it is not a direct indicator of how heat is absorbed or released in relation to temperature. Thus, the correct answer accurately reflects the specific concept of sensible heat and its effects on a substance.
