Gas Laws ch3

Question 1

Dalton’s law

(also called Dalton’s law of partial pressures)

Answer 1

in a mixture of non-reacting gases, the total pressure exerted is equal to the sum of the partial pressures of the individual gases.

Question 2

Pascal’s Principle

Answer 2

a fluid in equilibrium contained in a vessel exerts a pressure of equal intensity in all directions i.e. P1 = P2, P = F/A. => F1/A1 = F2/A2.

Question 3

Bernoulli’s Principle

Answer 3

The pressure of a moving fluid decreases as its speed increases.

Question 4

Boyle’s Law

Answer 4

for a fixed amount of gas at a constant temperature, the volume of the gas increases as the pressure of the gas decreases, and the volume of the gas decreases as the pressure of the gas increases. P1V1 = P2V2.

Question 5

Charles’s Law

Answer 5

for a fixed amount of gas at constant pressure, the volume of gas increases as the temperature of gas increases, and the volume of gas decreases as the temperature of gas decreases

Question 6

Ideal Gas Law

Answer 6

PV = nRT, n number of moles; R universal gas constant, T temperature.

Question 7

Gay-Lussac’s Law

Answer 7

The pressure of gas at constant volume is directly proportional to the absolute temperature.

Question 8

Avogadro’s Law

Answer 8

Equal volumes of gases under identical conditions of pressure & temperature contain the same number of molecules. The molar volume of all ideal gases at T=0 Celsius & P = 1 atm is 22.4 L.
