Delta T describes the difference in what quantity?

Explanation:
Delta T is the change in temperature between two states. It shows how much the temperature has increased or decreased, defined as ΔT = T2 − T1. This concept is used to describe heating or cooling across a component or in a space—for example, the temperature rise across a coil or the difference between outdoor and indoor temperatures. It’s a temperature quantity, not a difference in pressure, humidity, or velocity (which would be ΔP, ΔRH, or ΔV). For instance, if air goes from 60°F to 80°F, ΔT is 20°F.
