Gas Laws and Behavior

Flashcards covering key concepts related to gas laws and behavior, including laws, equations, and definitions.

What does the Ideal Gas Law equation PV = nRT represent?

It relates pressure (P), volume (V), number of moles (n), and temperature (T) using the universal gas constant (R).

What is the value of the universal gas constant R when using atm for pressure?

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

What happens to the pressure of a gas if its volume increases and the amount of gas remains the same?

According to Boyle's law, the pressure decreases as volume increases.

At standard temperature and pressure (STP), what volume does one mole of gas occupy?

One mole of any gas occupies 22.4 L at STP (0 °C and 1.00 atm).

How is pressure defined?

Pressure is defined as force per unit area (P = F/area).

What does Charles' Law state about the relationship between gas volume and temperature?

Charles' Law states that volume is directly proportional to temperature (V/T = a constant).

What happens to the pressure of a gas if the temperature increases while the volume remains constant?

The pressure increases according to Gay-Lussac's law.

According to Avogadro's Law, what is the relationship between volume and number of moles of gas?

Volume is directly proportional to the number of moles of gas (V/n = a constant).

What is Dalton’s Law of Partial Pressures?

In a mixture of non-reacting gases, the total pressure is equal to the sum of the partial pressures of the individual gases (P_tot = P1 + P2 + P3 + …).

What unit is commonly used to measure pressure in gas laws?

Common units include atm, mmHg, torr, kPa, and pascal.
