It is possible to reach absolute zero

• true
• false

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

• More rapidly at an increased diestance 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.

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.

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.
