Thermal Energy Quiz 1

A measure of the average kinetic energy of the molecules.

• potential energy

• kinetic energy

• thermal energy

• temperature

Answer explanation

Temperature measures the kinetic energy of an object's molecules.

Low-temperature particles have____________.

• Low average kinetic energy

• No average kinetic energy

• High average kinetic energy

• Extremely high average kinetic energy

How does a thermometer measure temperature?

• Temperature change causes the level of the liquid to rise and fall because of magic

• Temperature changes cause the level of the liquid to rise and fall because of the particle motion

• Temperature changes cause the liquid to rise when its cold and go down when it’s hot

• No one knows how they work

What unit is heat measured in?

• Kilowatts

• Joules

• Grams

• Pounds

In which state of matter do particles move fastest?

• Solid

• Liquid

• Gas

In which state of matter do particles move the slowest?

• Solid

• Liquid

• Gas

4. If the atoms of an object are moving slowly, the object would feel...

• cold or cool.

• hot or warm.

• unknown.

• smooth.

Answer explanation

Remember, temperature is the measure of the kinetic energy of the object. So if the atoms in the object are moving slowly, the objects kinetic energy is low and so is the temperature.

3. If the atoms of an object are moving fast and continue to move faster the temperature would be...

• increasing.
• decreasing.
• staying the same.
• freezing.
