# Thermodynamics Q=mc Delta T

The zeroth law of thermodynamics says that no heat is transferred between two objects in thermal equilibrium; therefore, they are the same temperature. We can calculate the heat released or absorbed Q using the specific heat capacity c , the mass of the substance m, and the change in temperature ΔT delta, T in the equation: Q = m c ΔT
