Thermodynamics Quiz

Temperature is a measure of the...

• total energy in a substance
• total kinetic energy in a substance
• average potential energy in a substance
• average kinetic energy of molecules in a substance

The total potential and kinetic energy of all the microscopic particles in an object make up its

• chemical energy.

• electric energy.

• nuclear energy.

• thermal energy.

Thermal energy is measured in 

• joules
• grams
• degrees celcius

High temperature is connected to:

• Low kinetic energy.
• High kinetic energy.
• Zero net energy.
• Equal kinetic energies.

Thermal energy always moves:

• From a high temperature object to a lower temperature object.
• From a lower temperature object to a higher temperature object.
• From an object with lower kinetic energy to an object with higher kinetic energy.
• From an object of higher mass to an object of lower mass.
