The specific heat of foam is 1200J(kg-K). How much heat does it take to raise the temperature of 1 kg of foam by 2 K?
Hint: Remember the Energy Change Formula Energy Change=Mass x Specific Heat x Temperature Change
The amount of energy required to raise the temperature of 1 kilogram of a substance by 1 kelvin is called its
change of state
melting point
specific heat
A material that conducts heat poorly is called a(n)
insulator
conductor
metal
