Review of Gas Laws

Flashcards created to review essential concepts from the Gas Laws lecture, focusing on formulas, relationships, and key principles.

What is the objective of the Gas Laws lecture?

To be able to solve the gas laws formula to determine pressure, volume, and temperature.

According to Boyle's Law, how does the volume of a fixed mass of gas vary with pressure at constant temperature?

The volume varies inversely with pressure; as volume decreases, pressure increases.

What temperature and pressure conditions make a gas behave most like an ideal gas?

High temperatures and low pressures.

What is the formula for Boyle's Law?

P1V1 = P2V2 (at constant temperature).

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

Pressure decreases.

What happens to the number of collisions if the volume is decreased?

The number of collisions increases.

What is the result of doubling the temperature of a gas at constant pressure according to Charles's Law?

The volume will double.

What is absolute zero?

The temperature at which there is no molecular motion, corresponding to 0 Kelvin.

What is Gay-Lussac's Law?

If the temperature of a gas sample in a closed container increases, the pressure also increases, and vice versa.

How do you find the new volume of a gas at standard temperature after cooling?

Use the formula V1/T1 = V2/T2 and convert temperatures to Kelvin.

At standard pressure, what is the standard pressure in torr?

760 torr.

What happens to the internal pressure of a gas in an aerosol can when heated in a fire?

The internal pressure increases.
