Temperature and Heat




• Thermal energy is total energy due to molecular & atomic motions within a substance.


• Temperature is average molecular energy within a substance.


• Heat is the flow of energy.


• Different substances are slower or faster at exchanging heat.


• Water is weird!




Useful Equations!


To change between temperature scales

°C = (°F-32) * 5/9


Length change due to heating

ΔL = α* L * ΔT


Heat needed to change mass by x degrees

Q  =  c * m * ΔT
