This is actually the ________ of the weight of the gas above an object on a given surface area. The higher the elevation, the lower the atmospheric pressure exerted because there is less air pressing down on the object.

• Temperature

• Pressure

• Measurement

• Force

It is also important to figure out the pressure under water or in a liquid. The ______ under water increases with how deep you are.

• Measurement

• pressure

• temperature

Critical Thinking! If gas particles in a tire are moving slowly, your tire pressure will drop because the gas particles are not pressing against the walls of the tire. What temperature change do you think would cause this pressure drop?

• The temperature will have become colder

• The temperature will have become hotter

• Temperature and pressure have no relation

Answer explanation

The correct choice is 'The temperature will have become colder' because a decrease in temperature causes gas particles to move more slowly, resulting in a drop in tire pressure.

We often think of the states of matter changing from solid to liquid or liquid to gas based on the temperature, but the _______ also has an impact on the state. In most cases, the higher the pressure, the higher the ________ needed to change the state.

• Pressure

• State

• Temperature

• Liquid
