Work out specific heat capacity instantly with clear inputs, formula shown and shareable results.
Specific heat capacity is the heat needed per kilogram per kelvin, so it follows from c = Q/(m.dT). 20 kJ raising 2 kg by 12 K gives 833 J/(kg K), in the range of glass and aluminium. Water's 4186 J/(kg K) is exceptionally high, which is why it makes such an effective coolant and thermal store.
Specific heat capacity
c = Q / (m x dT)
Sample heat capacity
C = m x c
Hydrogen bonding stores energy in bond bending and stretching as well as molecular motion, so more energy is needed per degree.
Somewhat. For solids it rises towards the Dulong-Petit limit and falls sharply near absolute zero, but over ordinary ranges a constant value is fine.
