Atmospheric Pressure and Liquid Pressure

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

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
