Review on Heat and Temperature

If a hot liquid is poured into a cup, the cup will soon feel warm. How does the increase in temperature change the particles that make up the cup?

• They move less freely.

• They move closer together.

• Their kinetic energy

  increases.

• They move from place to

  place.

Which of these choices describes the thermal energy of a substance?

• sum of the kinetic energy of all of the particles of a substance

• average kinetic energy of

  the particles that make up a substance

• total kinetic and potential energies of the particles of a substance

• difference between the

  kinetic energy and potential energy of a substance

What is heat?

• total thermal energy of an

  object or substance

• change in the temperature of

  a substance in degrees Celsius

• energy transferred between

  objects at different temperatures

• average kinetic energy of the particles that make up a substance

What temperature does the thermometer show?

• 1°C

• - 1°C

• 2°C

• - 2°C

How does heat affect the thermal energy of an object that is colder than the air that surrounds it?

• Heat decreases the thermal

  energy of an object as energy moves to the air.

• Heat causes the thermal

  energy of the object to increase as energy moves from the warmer air to the

  colder object.

• Heat has no effect on

  thermal energy, but it increases the potential energy of an object.

• Heat is not related to

  thermal energy, so it cannot affect the thermal energy of an object.

Andrew puts a beaker of ice and water on a hot plate, and the ice slowly begins to melt. After a few minutes, only liquid water is in the beaker. Eventually, the water becomes hot and boils. The liquid water changes to water vapor, which is a gas.In what way is the liquid water different from the water vapor?

• The liquid particles move

  slower.

• The liquid has a higher

  boiling point.

• The vapor has a lower

  temperature.

• The vapor particles have

  less energy.
