Many scientific measurements use the Kelvin temperature scale (unit symbol: K), named in honor of the physicist who first defined it. It is an absolute scale. Its numerical zero point, 0 K, is at the absolute zero of temperature. Since May 2019, the kelvin has been defined through particle kinetic theory, and statistical mechanics.

The symbol Q for heat was introduced by Rudolf Clausius and Macquorn Rankine in c. 1859. [4] ... manifest as temperature change, ... Thermal Physics, ...
In thermal physics and thermodynamics, ... The symbol γ is used by ... with ΔT representing the change in temperature.
A temperature coefficient describes the relative change of a physical property that is associated with a given change in temperature. For a property R that changes when the temperature changes by dT , the temperature coefficient α is defined by the following equation:
