Ideal Gas Laws

Front

What does R stand for in the Ideal Gas Law?

Back

R stands for the Ideal gas constant.

Front

Which formula is used to relate pressure, volume, and temperature in gas law calculations?

Back

The formula is P1V1/T1 = P2V2/T2.

Front

What is the total pressure in a container with Ar at 255 torr, N2 at 228 torr, and H2 at 752 torr?

Back

The total pressure is 1235 torr.

Front

What is the pressure at Standard Temperature and Pressure (STP) in atmospheres?

Back

The pressure at STP is 1 atm.

Front

In which temperature scale must temperature be measured for gas law calculations?

Back

Temperature must be measured in Kelvin.

Front

What is the Ideal Gas Law equation?

Back

The Ideal Gas Law is PV=nRT.

Front

What does the variable 'n' represent in the Ideal Gas Law?

Back

The variable 'n' represents the number of moles of gas.

Front

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

Back

R = 0.0821 L·atm/(K·mol).

Front

What happens to the volume of a gas if the temperature increases while pressure remains constant?

Back

The volume of the gas increases (Charles's Law).

Front

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

Back

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