Unit 8: Gas Laws Review

Front

What is the Ideal Gas Law?

Back

The Ideal Gas Law is a fundamental equation in chemistry that relates the pressure (P), volume (V), temperature (T), and number of moles (n) of an ideal gas: PV = nRT, where R is the ideal gas constant.

Front

What happens to the pressure of a gas when its volume decreases at constant temperature?

Back

According to Boyle's Law, if the volume of a gas decreases while the temperature remains constant, the pressure of the gas increases.

Front

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

Back

According to Gay-Lussac's Law, the pressure of a gas is directly proportional to its absolute temperature when the volume is held constant.

Front

How do you convert Kelvin to Celsius?

Back

To convert Kelvin to Celsius, subtract 273.15 from the Kelvin temperature: °C = K - 273.15.

Front

What is Charles's Law?

Back

Charles's Law states that the volume of a gas is directly proportional to its absolute temperature when pressure is held constant.

Front

What is the effect of increasing temperature on gas pressure?

Back

Increasing the temperature of a gas at constant volume increases the pressure, as per Gay-Lussac's Law.

Front

What is the formula for Boyle's Law?

Back

Boyle's Law is expressed as P1V1 = P2V2, where P is pressure and V is volume.

Front

What is the significance of the gas constant (R) in the Ideal Gas Law?

Back

The gas constant (R) is a proportionality constant that relates the energy scale to the temperature scale in the Ideal Gas Law.

Front

What happens to gas molecules when temperature increases?

Back

When temperature increases, gas molecules gain kinetic energy, move faster, and collide more frequently with the walls of their container, increasing pressure.

Front

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

Back

According to Avogadro's Law, the volume of a gas is directly proportional to the number of moles of gas when temperature and pressure are constant.
