Lesson 3: Changes in Pressure

Front

What is pressure?

Back

Pressure is the measurement of force applied per unit area.

Front

How does pressure relate to volume?

Back

As pressure increases, volume decreases, and vice versa (Boyle's Law).

Front

What happens to gas pressure when more particles are added to a container?

Back

The pressure inside the container increases as more gas particles are added.

Front

What is the relationship between the size of a container and gas volume?

Back

As the space in a container gets smaller, the volume of gas decreases.

Front

What device can heat water above its boiling point?

Back

A pressure cooker can heat water hotter than its boiling point.

Front

What is Boyle's Law?

Back

Boyle's Law states that the pressure of a gas is inversely proportional to its volume at constant temperature.

Front

What happens to gas pressure if the temperature increases?

Back

If the temperature increases, the pressure of the gas also increases if the volume is constant (Gay-Lussac's Law).

Front

What is the formula for calculating pressure?

Back

Pressure = Force / Area.

Front

What is atmospheric pressure?

Back

Atmospheric pressure is the pressure exerted by the weight of the atmosphere above a surface.

Front

What is a vacuum?

Back

A vacuum is a space where there is little to no matter, resulting in very low pressure.
