## Problem 1: Part 2: Energy equationEdit

For an adiabatic process, the rate of change of temperature can be written as

where is the Taylor-Quinney coefficient, is the density, and is the specific heat. Express in terms of and . This is the evolution law for .

Plugging in the expression for , we get
