Specific heat capacity (J/g oC) is the amount of heat required to raise the temperature of one gram of a substance by 1°C one Celsius . Specific heat capacity only depends on the kind of substance. For example, 100 g of gold will have the same specific heat capacity as 1 kg of gold.
Water has a relatively high specific heat (~4.2 J/g oC for liquid, 2.09 J/g oC for solid ) compare to metals (mostly less than 1 J/g oC). Therefore, it's easier to heat metal than water. of approximately 4.2 joules over grams per celsius for liquid and 2.09 joules over grams per celsius for solid compared to metals, which is mostly less than 1 joules over grams per celsius. Therefore, it's easier to heat metal than water .
