When two objects in contact reach the same temperature
A change of 1°C equals a change of 1 K
Temp. is how hot; quantity of heat is total thermal energy
Amount of heat energy is proportional to the mass
Depends on the nature of the substances involved
Heat to raise unit mass by 1°C (or 1 K)
4.18 J K−1g−1\text{J K}^{-1} \text{g}^{-1}J K−1g−1 (highest of common substances)
q=mcΔTq = mc\Delta Tq=mcΔT
Heat gained (endothermic, temperature increased)
Heat lost (exothermic, temperature decreased)
