Thermal equilibrium is a complex way of saying, if we have two objects that are ​ (a)   temperatures, eventually they will end up ​ (b)   temperature.

• different
• the same

When you have two objects with varying temperatures, thermal energy will flow from the ​ (a)   object to the object with the ​ (b)   until they obtain ​ (c)   .

• higher temperature
• lower temperature
• thermal equilibrium
• opposite temperature
• thermal imbalance

Thermal energy always travels from the

• higher temperature to lower temperature
• equal temperature to equal temperature
• from the ground to the sky
• from cold objects to hot objects
• lower temperature to higher temperature

Which statement best explains why liquid water stores more thermal energy than an equal amount of any other naturally occurring substance?

• Liquid water evaporates quickly, reducing thermal energy storage.
• Liquid water has a higher viscosity than other liquids.
• Liquid water has a low boiling point compared to other substances.
• Liquid water is less dense than most liquids.
• Liquid water stores more thermal energy due to its high specific heat capacity.

Bob orders a cup of coffee.  The coffee is very hot.  Bob places an ice cube in his coffee.  Describe the movement of the thermal energy in the cup. 

• Thermal energy moves from the ice cube to the coffee, cooling the coffee.

• Thermal energy remains constant and does not move between the coffee and the ice cube.
• Thermal energy moves from the ice cube to the air, cooling the coffee.
• Thermal energy moves from the coffee to the cup, leaving the ice cube unchanged.
• Thermal energy moves from the hot coffee to the ice cube, cooling the coffee and melting the ice.
