Observable Properties of Gases Fun

Front

What is a barometer?

Back

A barometer is an instrument invented by Torricelli to measure air pressure.

Front

How much more space does water vapor occupy compared to the same mass of liquid water?

Back

Water vapor occupies over 1000 times more space than the same mass of liquid water.

Front

What law explains the relationship between pressure and volume of a gas at constant temperature?

Back

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

Front

What happens to the average speed and total kinetic energy of gas molecules when heated?

Back

As the temperature increases, the average speed and total kinetic energy of gas molecules increase.

Front

Why is there gas pressure inside a closed container?

Back

Gas pressure exists because gas molecules collide constantly with the walls of the container.

Front

What is the Ideal Gas Law?

Back

The Ideal Gas Law is a formula (PV=nRT) that relates the pressure, volume, temperature, and number of moles of a gas.

Front

What is Avogadro's Law?

Back

Avogadro's Law states that equal volumes of gases at the same temperature and pressure contain an equal number of molecules.

Front

What is Charles's Law?

Back

Charles's Law states that the volume of a gas is directly proportional to its temperature when pressure is held constant.

Front

What is the kinetic molecular theory?

Back

The kinetic molecular theory explains that gas molecules are in constant random motion and that their collisions with the walls of a container create pressure.

Front

What is the relationship between temperature and kinetic energy of gas molecules?

Back

The kinetic energy of gas molecules increases as the temperature increases.
