Physics and Thermodynamics

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

A(n) _____________ is a device for measuring temperature.

• thermometer
• barometer
• anemometer
• psychrometer 

When thermal energy is added to a substance, the substance's particles move:

• More rapidly at an increased distance from each other.

• More rapidly with less distance between each other.

• More slowly with a greater distance between each other.

• More slowly with a reduced distance between each other.
