Answer to Question #7547 in Molecular Physics | Thermodynamics for Loren

Question

What equation should I use for the internal heat energy of something?

Answer 1

The amount of heat needed to heat a subject from one temperature level to an other can be expressed as:

Q = cp*m*dT,

where:
Q = amount of heat (kJ);
cp = specific heat (kJ/kg.K);
m = mass (kg);
dT = temperature difference between hot and cold side (K).
