6th Science Lesson 2-3 Gas Behavior Review

Front

What is pressure?

Back

The pressure of a gas is the force of its outward push (in Newtons) over an area (in square meters) of the walls of the container.

Front

How is the pressure of a gas measured?

Back

Pressure is measured in units of pascals (Pa) or kilopascals (kPa).

Front

What happens when you heat a gas?

Back

When you heat a gas, its particles move faster, so the temperature increases.

Front

What happens when the temperature of a gas at constant volume is increased?

Back

When the temperature of a gas at constant volume is increased, the pressure of the gas increases.

Front

What happens when the temperature of a gas at constant volume decreases?

Back

When the temperature of a gas at constant volume is increased, the pressure of the gas decreases.

Front

What did French scientist Jacques Charles discover about the relationship between the temperature and volume of a gas?

Back

French scientist Jacques Charles discovered that when the temperature of a gas at constant pressure is increased, its volume increases. He also discovered that when the temperature of a gas at constant pressure is decreased, its volume decreases.

Front

What did the scientist Robert Boyle discover about the relationship between the pressure and volume of a gas?

Back

Boyle discovered that when the pressure of a gas at constant temperature is increased, the volume of the gas decreases. He also discovered that when the pressure is decreased, the volume increases.

Front

How does the pressure of a gas change according to Boyle’s Law?

Back

The pressure changes in the opposite way.
