How is sensible heat observed?

Sensible heat is the heat that causes a change in temperature of a substance without changing its state or phase. It can be directly observed through the use of a thermometer, which measures the temperature of a substance. When sensible heat is added to or removed from a material, the temperature will increase or decrease, and this change can be quantified through the readings on a thermometer.

This process is distinct from latent heat, which is associated with phase changes, such as melting or boiling, where the temperature remains constant during the transition. Because sensible heat is directly linked to temperature changes and easily measurable with a thermometer, this is how we observe it effectively in practical applications.
