Kinetic Molecular Theory and Gas Laws

These flashcards cover key concepts from the lecture on Kinetic Molecular Theory and Gas Laws.

What does the kinetic molecular theory state about gas particles?

Gas particles move independently and they do not attract or repel each other.

What happens to the average energy of gas particles as temperature increases?

The average energy of gas particles increases.

What relationship does Boyle's Law describe?

Boyle's Law states that volume and pressure are inversely related if other variables are held constant.

What does the Ideal Gas Law relate?

The Ideal Gas Law relates volume, pressure, temperature, and number of moles of gas.

What is the value for the molar volume of any gas at STP?

The molar volume of any gas at STP is 22.4 L.

What is the temperature in Kelvin for STP?

273 K.

Who formulated the principle that sum of partial pressures equals total pressure?

Dalton.

What must temperature always be in when using gas laws?

Temperature must always be in Kelvin.

What is the equation for R in the Ideal Gas Law?

R = 0.0821 L(atm)/(mol)(K).

What is the result of compressing gas at constant temperature according to Boyle's Law?

As the volume decreases, the pressure increases.

In Avogadro's Law, what does 'n' stand for?

'n' stands for moles.

What is the partial pressure of a gas in a mixture?

It is the pressure that the gas would exert if it occupied the entire volume alone.

How is the pressure affected by the number of gas particles present?

Pressure is directly affected by the number of gas particles present; more particles increase pressure.
