How it's calculated

Q = m × c × ΔT
Q/t = k × A × ΔT ÷ d

Specific heat is the energy to warm 1 kg by 1 K: water takes 4186 J, which is why it heats slowly and stores so much. Conduction moves heat through a solid at a rate set by its conductivity, area, the temperature difference and its thickness. Values are typical at room temperature; real materials vary.
