How do the specific heats of metals compare with water? …

15/3/2014· The specific heat of metals are lower than that of water. Specific heat capacity is the measurement of how much energy (in J) has to be added to 1 kg of a substance to increase the temperature of that substance by 1^oC. Simply, substances with a low specific heat capacity heat up quickly - but then they lose their heat quickly. Substances with a high specific heat capacity require a …
