Heat & Materials

Energy Change = Mass X Specific Heat X Temperature Change. What do they mean by “specific heat”?

• The ability of a material to change temperature quickly
• The temperature required to boil the material
• The heat energy lost when a material cools
• The amount of energy needed to raise the temperature of 1 kg of a material by 1 Kelvin

An example of an insulator would be...

• Copper
• Aluminum
• Wood
• Steel
