Specific heat of water is  4.18 J/g°C. Specific heat of wood is 1.760 J/g°C What material needs more heat energy to raise the temperature?

• Water
• Wood
• Both are same

A high specific heat means...

• It heats up quickly with energy added
• It requires more energy to change temperature

If two objects have different temperatures, thermal energy will

• the warmer object to the cooler object

• the cooler object to the warmer object

• stay the same

• not get lost or destroyed

As you increase temperature

• molecules speed up and spread apart

• molecules speed up and get closer together

• molecules slow down and spread apart

• molecules slow down and get closer together

Particles closest together

• solid
• liquid
• gas
• solid, liquid and gas
