Outcome 3

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

• True
• False

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

• temperature
• heat
• internal energy
• none of these

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.

Heat transfer by conduction occurs when...

• particles bump into each other
• large numbers of atoms move from place to place
• atoms give off heat in the form of electromagnetic waves
• electromagnetic waves travel from place to place through a vacuum

Heat transfer by convection occurs when...

• electrons bump into other electrons
• large numbers of atoms move from place to place
• atoms give off heat in the form of electromagnetic waves
• electromagnetic waves travel from place to place through a vacuum

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.

The second  law of thermodynamics states that entropy of a system  tends to ______________. 

• increase
• decrease
• stay constant
• fluctuate wildly

The temperature of a glass of cold water will eventually...

• Match the temperature of the surrounding environment.
• Always be colder than the surrounding environment.
• Become warmer than the surrounding environment.
• Never change temperature.
