ideal gas

What is the definition of an ideal gas?

An ideal gas is a theoretical gas composed of many randomly moving point particles that interact only when they collide elastically.

What is the purpose of the ideal gas model?

The ideal gas model simplifies the complex behavior of real gases and provides a foundation for understanding gas laws.

What does Boyle's Law state?

Boyle’s Law states that the pressure of a given amount of gas is inversely proportional to its volume when the temperature and the number of particles are held constant.

What is the mathematical expression for Boyle's Law?

P1V1 = P2V2 where P1 and P2 are the initial and final pressures, and V1 and V2 are the initial and final volumes.

What happens to pressure if the volume of a gas decreases?

If the volume of a gas decreases, the pressure increases, provided temperature and number of gas particles remain constant.

What does Charles's Law state?

Charles's Law states that the volume of a given amount of gas is directly proportional to its absolute temperature when pressure and the number of gas particles are held constant.

What is the mathematical expression for Charles's Law?

V1/T1 = V2/T2 where V1 and V2 are the initial and final volumes, and T1 and T2 are the initial and final temperatures.

According to Avogadro's Law, how is volume related to the number of moles?

Avogadro’s Law states that the volume of a gas is directly proportional to the number of moles of gas present, provided the pressure and temperature are constant.

What is the mathematical expression for Avogadro's Law?

V1/n1 = V2/n2 where V1 and V2 are the initial and final volumes, and n1 and n2 are the initial and final number of moles of the gas.

What does Gay-Lussac's Law state?

Gay-Lussac’s Law states that the pressure of a gas is directly proportional to its absolute temperature when the volume and the number of gas particles are constant.

What is the mathematical expression for Gay-Lussac's Law?

P1/T1 = P2/T2 where P1 and P2 are the initial and final pressures, and T1 and T2 are the initial and final temperatures.

What is the Combined Gas Law?

The Combined Gas Law combines Boyle’s, Charles’s, and Gay-Lussac’s laws into a single equation, showing the relationship between pressure, volume, and temperature when the number of particles is constant.

What is the mathematical expression for the Combined Gas Law?

P1V1/T1 = P2V2/T2 where P1, V1, T1 are initial values and P2, V2, T2 are final values.

What is the Ideal Gas Law?

The Ideal Gas Law is a fundamental equation that relates the pressure, volume, temperature, and number of moles of an ideal gas.

What is the equation for the Ideal Gas Law?

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

How can you rearrange the Ideal Gas Law to find the number of moles?

You can rearrange it to n = PV/RT.
