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 is Boyle's Law?

Back

Boyle's Law states that the pressure of a gas is inversely proportional to its volume when temperature is held constant: P1V1 = P2V2.

Front

What is Charles's Law?

Back

Charles's Law states that the volume of a gas is directly proportional to its temperature (in Kelvin) when pressure is held constant: V1/T1 = V2/T2.

Front

What is Gay-Lussac's Law?

Back

Gay-Lussac's Law states that the pressure of a gas is directly proportional to its temperature (in Kelvin) when volume is held constant: P1/T1 = P2/T2.

Front

How do you convert Celsius to Kelvin?

Back

To convert Celsius to Kelvin, add 273.15 to the Celsius temperature: K = °C + 273.15.

Front

What is the formula for calculating pressure in a gas?

Back

Pressure can be calculated using the formula: P = F/A, where P is pressure, F is force, and A is area.

Front

What happens to gas volume when temperature increases at constant pressure?

Back

According to Charles's Law, the volume of a gas increases as the temperature increases at constant pressure.

Front

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

Back

According to Boyle's Law, as the volume of a gas decreases, its pressure increases, provided the temperature remains constant.

Front

What is the significance of the absolute zero temperature?

Back

Absolute zero (0 K) is the theoretical temperature at which a gas would have zero volume and pressure, indicating no molecular motion.

Front

What is the combined gas law?

Back

The combined gas law combines Boyle's, Charles's, and Gay-Lussac's laws: (P1V1)/T1 = (P2V2)/T2.
