An object with a higher temperature can have less thermal energy than an object with a lower temperature.

• True

• False

Only matter that feels warm has thermal energy.

• True

• False

Anything that is moving has (a)   energy.

Why do molecules and atoms have kinetic energy?

• because they are in motion

• because they are at rest

• because they are hot

• because they are cold

Which property is dependent on the amount of matter present?

• temperature

• density

• thermal energy

• heat

The temperature at which molecular motion stops is (a)  

The Kelvin temperature scale is based on

• the melting point and boiling point of oxygen

• kinetic energy of the particles in a sample of matter

• the coldest temperature ever recorded

• mercury

On which temperature scale is "Absolute Zero" measured:

• Fahrenheit

• Celsius

• Kelvin

• Rankine

When an object cools, it

• gains cold energy

• loses cold energy

• loses thermal energy

• gains thermal energy

The same amount of thermal energy is added to a 5-g block of iron and a 5-g block of aluminum. After heating, the iron block is noticeably hotter than the aluminum block. Which substance has the higher specific heat?

• Iron

• Aluminum

• They have the same specific heats.
