What's Compressibility?

Measure if how much the volume matter decreases under pressure.


Why are gases easier to compress Tara solids or liquids?

Because of the space between the particles in a gas.


Three factors that affect gas pressure?

1- amount of gas
2- volume
3- temperature


How are the pressure and volume of gas related?

If the temperature is constant as the pressure of a gas increases the volume decreases.


What's Boyles law?

States for a given mass if gas at constant temperature, the volume of the gas varies inversely with pressure.


What's Charles law?

States that the volume if a fixed mass if gas is directly proportional to it's kelvin temperature if pressure is kept constant.


How are the pressure and temperature of gas related?

As the temperature if an enclosed gas increases the pressure increases if the volume is constant.


What's Gay-Lussacs law?

States that the pressure of a gas is directly proportional to the kelvin temperature if volume remains constant.


Under what conditions are real gases most likely to differ from ideal gases?

At low temperature and high pressures.


What's Partial pressure?

Contribution each gas in a maritime makes to the total pressure.


How is the total pressure of a gas mixture related to the partial pressure of the component gases?

The total pressure is the sum if the partial pressure if the gases.


What's Dalton's law of partial pressure?

At constant volume and temperature total pressure exerted by a mixture of gases is equal to the sum of partial pressure of the component gases.


What's Diffusion?

Tendency of molecules to move towards areas of lower concentration until is uniform throughout.


What's Effusion?

Gas escapes through a tiny hole in its container.


How does molar mass of a gas affect the rate at which the gas diffuses effuses?

Lower molar mass diffuses and effuses fasted that gases of higher molar mass.


What's Graham's law of effusion?

Rate of effusion of a gas is inversely proportional to the square riot of the gases molar mass.
