Does metal have a high heat capacity? No, metals do not have high heat capacities, and this is why they are good conductors of heat. This property makes them useful for creating kitchen utensils. What is the specific heat of water? The specific heat for water in the liquid phase is 4.19...
Heat capacity also depends on the material of the object. Some materials are harder to heat up than others. The molecules in a liquid such as water require more energy to move faster than copper atoms in a solid. So, in order to record 1°C increase in temperature, liquids would require...
