Gas Law TEST

Front

What are the three main properties of gases?

Back

Pressure, Volume, Temperature.

Front

TRUE or FALSE: The properties of gases (pressure, volume, temperature) are all directly proportional to each other.

Back

FALSE

Front

What is the formula to calculate pressure in a gas?

Back

Pressure (P) = Force (F) / Area (A).

Front

What happens to the volume of a gas when the temperature increases?

Back

The volume of a gas generally increases with an increase in temperature (Charles's Law).

Front

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

Back

Pressure and volume are inversely proportional (Boyle's Law).

Front

If a gas has a volume of 3.50L at 200K, what is the new temperature if the volume changes to 7L?

Back

400K.

Front

What is the ideal gas law equation?

Back

PV = nRT, where P = pressure, V = volume, n = number of moles, R = ideal gas constant, T = temperature.

Front

How do you calculate the molecular weight of a gas?

Back

Molecular weight = mass of gas (g) / number of moles (mol).

Front

If I have 2.00 moles of a gas at a temperature of 250K and a volume of 8.50 liters, what is the pressure?

Back

4.83 atm.

Front

What is the effect of increasing pressure on the volume of a gas?

Back

Increasing pressure decreases the volume of a gas (Boyle's Law).
