Gas Laws

Question 1

What is Boyle’s Law?

Answer 1

The pressure excreted by a fixed amount of gas, at constant Kelvin temperature is inversely proportional to the volume.

Question 2

Equation to calculate pressure or volume of gases at a fixed temperature.

Answer 2

P1V1 = P2V2

Question 3

What is the equation for thermal expansivity?

Answer 3

Difference in volume / initial volume = thermal expansivity

Question 4

What is Charles Law equation

Answer 4

V1 / T1 = V2/ T2

Question 5

What is Charles Law

Answer 5

At a constant pressure the volume of a given mass of any gas is directly proportional to the Kelvin temperature

Question 6

What is the Ideal Gas Law

Answer 6

PV = nRT
PV = NKT

Question 7

What does the R stand for in PV = nRT

Answer 7

The universal gas constant

Question 8

What formula can be derived from the combined gas laws?

Answer 8

P1V1 / T1 = P2V2 / T2

Question 9

What is Avogadro’s Law

Answer 9

Equal volumes of gases under the same conditions of temperature, pressure, contain equal number of molecules

Question 10

What is the Boltzman’s constant?

Answer 10

R/ Na
