Multiple Choice

Heat flows from _______ to ______ objects

• cooler to warmer

• warmer to warmer

• warmer to cooler

• cooler to cooler

Multiple Choice

A slower particle has a lower energy than an identical, faster particle.

• True
• False

Multiple Choice

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

• temperature

• heat

• internal energy

• none of these

Multiple Choice

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.

Multiple Choice

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.
