Ideal Gas Laws

Front

What are the four measurable properties of gases?

Back

Pressure, Temperature, Volume, and Moles.

Front

What happens to the volume of a gas when the number of moles increases?

Back

The volume goes up.

Front

What is the Kelvin temperature required for 0.0470 mol of gas to fill a balloon to 1.20 L under .998 atm pressure?

Back

307 K.

Front

What is the standard pressure at STP in atmospheres?

Back

.0069 mol.

Front

What is the Ideal Gas Law equation?

Back

PV = nRT.

Front

What does 'R' represent in the Ideal Gas Law?

Back

R is the ideal gas constant.

Front

What is the value of the ideal gas constant (R) in L·atm/(K·mol)?

Back

Front

What is the relationship between pressure and volume in Boyle's Law?

Back

Pressure and volume are inversely related.

Front

What does Charles's Law state about the relationship between volume and temperature?

Back

Volume is directly proportional to temperature (in Kelvin).
