Why does water heat heat up and cool down VERY SLOWLY?

• High Specific Heat

• Low Specific Heat

• It's solid

• It's always cold

A high specific heat means...

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

What does temperature measure?

• Heat
• ºC
• Kinetic Energy
• Thermal Energy

Heat ALWAYS moves from

• Low to High Temperature

• High to Low Temperature

• It doesn't move

• High to Low Pressure
