Heat

Heat is energy in transit

Heat is energy in transit that flows from higher temperature to lower temperature bodies (measured in Joules or calories). Temperature is the measure

When two bodies in contact reach

When two bodies in contact reach the same temperature, they achieve thermal equilibrium - no net heat transfer occurs. The thermometer reading at this

The amount of heat required

The amount of heat required to raise the temperature of unit mass of a substance by one degree. Formula: S = Q/(mΔT), where S is specific heat, Q is h

When substances at different temperatures mix

When substances at different temperatures mix, heat lost by hotter substances equals heat gained by colder substances until thermal equilibrium. Formu

Surface phenomenon where liquid molecules escape

Surface phenomenon where liquid molecules escape into gas phase at any temperature. Molecules with higher kinetic energy escape from the surface, leav
