How does a liquid-in-gas thermometer work?

• heat energy causes the liquid in the bulb to expand and rise up the tube

• heat energy causes the liquid in the bulb to contract and rise up the tube

• heat energy causes the liquid in the bulb to expand and fall down the tube

• heat energy causes the liquid in the bulb to contract and fall down the tube

What is meant by the range of a thermometer?

• the difference between the maximum and minimum temperature the thermometer can measure

• the average between the maximum and minimum temperature the thermometer can measure

• the smallest value the thermometer can measure

• the smallest difference the thermometer can distinguish

Which of these best describes evaporation?

• the escape of more-energetic molecules from the surface of a liquid

• the escape of more-energetic molecules from the surface of a gas

• the escape of less-energetic molecules from the surface of a liquid

• the escape of less-energetic molecules from the surface of a gas

Which of these describes the random bombardment of air molecules?

• Brown motion

• Brownian motion

• Bromine motion

• Bronian motion
