Water has a specific heat of 4184 J/KgºC.  Wood has a specific heat of 1760 J/KgºC.  What material needs more energy to raise the temperature 1ºC

• Wood
• Water
• Both are the same

The amount of energy required to raise the temperature 1ºC for every kilogram is called____?

• Thermal Energy
• Specific Heat
• Temperature
• Kinetic Energy

A high specific heat means...

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

What would be the effect on the particles if more heat is supplied to the system?

• They would slow down
• They would stop moving
• They would speed up
• There would be no effect

There are four cups of hot cocoa. The cup sizes are shown. The temperature of the cocoa in each cup is 25 degrees celsius. Which cup has the MOST thermal energy?

• Large cup (Trenta)
• Small cup (Tall)
• Venti
• All three are the same temperature so they have same thermal energy
