Sensible heat is measured by which temperature parameter?

Explanation:
Sensible heat is the energy that changes the temperature of air or a substance without changing its phase. It is measured by the dry-bulb temperature, which is the actual air temperature read with a standard thermometer kept dry. The dry-bulb value reflects the amount of sensible heat present, making it the appropriate measure. In contrast, the wet-bulb temperature mixes temperature with humidity effects due to evaporative cooling, so it’s not a pure measure of sensible heat. Latent heat involves energy absorbed or released during phase changes, not a straightforward temperature change, and relative humidity indicates moisture content relative to saturation, not energy.
