Which of the following statements about the kinetic theory of gases is NOT true:
All molecules move with the same speed.
Their average kinetic energy is directly proportional to the absolute temperature.
All molecules make elastic collisions with each other and the walls of the container.
The molecules travel in straight lines until they collide.
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

Which of these describes the random bombardment of air molecules?
Brown motion
Brownian motion
Bromine motion
Bronian motion
What is the link between pressure and force?
there is no link between them
pressure is the force per unit area
