• average kinetic energy of molecules in a substance

A substance with a high specific heat:

• Is always extremely hot.
• Requires a lot of energy to become hot.
• Is not heavy.
• Does not requires a lot of energy to become hot.

The transfer of thermal energy between objects of different temperatures is called...

• temperature
• heat
• internal energy
• none of these

What is the correct formula to convert Celsius to Kelvin?

• K=C-273
• K=C+273

• K=C+100

What is entropy?

• A measurement of chaos
• The heat content of a system 

The temperature of a glass of cold water will eventually...

• Match the temperature of the surrounding environment.
• Always be colder than the surrounding environment.
• Become warmer than the surrounding environment.
• Never change temperature.

Total entropy increases over time.

• True
• False

Heat is measured in 

• joules
• grams
• degrees celcius
