What happens to the particles of a substance

when its temperature increases?

• They move slower

• They move faster

• They stay the same

• They stop moving

What is the relationship between

temperature and energy?

• They are directly proportional —

  when one increases, the other

  increases

• They are inversely proportional —

  when one increases, the other

  decreases

• They are unrelated

• Energy depends only on mass, not

  temperature

How does mass affect temperature

change when the same amount of

heat is added?

• A smaller mass heats up faster

• A larger mass heats up faster

• Both heat up at the same rate

• Mass does not affect temperature

Why is the equator warmer

than the poles?

• (a) It is closer to the Sun.

• (b) It receives more direct sunlight.

• (c) It has more land.

• (d) It spins faster.

What is the Coriolis Effect?

• (a) Earth’s tilt causing seasons.

• (b) The bending of moving air and

  water due to Earth’s rotation.

• (c) The heating of air near the

  equator.

• (d) The movement of ocean

  waves.

Which of the following statement correctly describes the relationship between kinetic energy and Volume of a substance?

•    An increase in kinetic energy causes thermal expansion

•     A decrease in kinetic energy causes thermal contraction

•    An increase in kinetic energy causes thermal contraction

•     There is no relationship between temperature and kinetic energy

Why does the handle of the pan stay cooler than the pan itself?

• The handle is made of a thermal conductor.

• The handle has a higher specific heat than the pan.

• The handle is a thermal insulator, while the pan is a thermal conductor.

• The handle absorbs more heat than the pan.

The temperature of a piece of iron increases more than that of a sample of water with the same mass when the same amount of thermal energy is added. This is because   .

•   iron has a higher specific heat

• iron has a lower specific heat

• iron has a higher melting point

•   water is a liquid and iron is a solid

 

Which process involves particles gaining energy and moving from a liquid to a gas state?

•      Freezing

• Condensation

• Melting

• Evaporation

Which method of thermal energy transfer does not require contact between objects?

•      Conduction

• Convection

• Radiation

• Reflection
