Module 12 Gases Pre-Test

Front

What does P1 / T1 = P2 / T2 represent?

Back

Gay-Lussac's Law

Front

Why does the pressure decrease as we reach higher elevations?

Back

Because there are less air molecules.

Front

What is the formula that combines Boyle's, Charles's, and Gay-Lussac's laws?

Back

P1V1/T1 = P2V2/T2, known as the Combined Gas Law.

Front

What do gases have enough of to overcome intermolecular forces?

Back

Kinetic energy.

Front

What happens to the volume of a balloon when placed in a refrigerator?

Back

It will decrease.

Front

What is Boyle's Law?

Back

At constant temperature, the pressure of a gas is inversely proportional to its volume.

Front

What is Charles's Law?

Back

At constant pressure, the volume of a gas is directly proportional to its temperature in Kelvin.

Front

What is Gay-Lussac's Law?

Back

At constant volume, the pressure of a gas is directly proportional to its temperature in Kelvin.

Front

What is the Ideal Gas Law?

Back

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

Front

What is Dalton's Law of Partial Pressures?

Back

The total pressure of a gas mixture is equal to the sum of the partial pressures of each individual gas.
