Chp 8 Gas Laws and equation

Question 1

Boyle’s law

Answer 1

For a fixed mass of a gas at constant temperature the pressure of the gas is inversely proportional to it’s volume
PV=K
P ₁V ₁=P₂V₂

Question 2

Charles’ Law

Answer 2

For a fixed mass of a gas at constant pressure the volume of the gas is directly proportional to its temperature in Kelvins
V/T=K
V₁/T₁=V₂/T₂

Question 3

Combined gas law

Answer 3

PV/T=K

Question 4

Gay-Lussac’s law of combining volumes

Answer 4

Gas reactants are in simple whole number ratios by volume with each other and their products

Question 5

Ideal gases

Answer 5

A gas which obeys the kinetic theory of gases at all conditions of temperature and pressure
PV=nRT

Question 6

Kinetic Theory of Gases
1st

Answer 6

Gas particles are in rapid, random straight line motion colliding with each other and with the wall of the container

Question 7

Kinetic Theory of Gases
2nd

Answer 7

The collisions between gas particles are elastic - Particles don’t lose energy when they collide

Question 8

Kinetic Theory of Gases
4th

Answer 8

The average kinetic energy of gas particles is directly proportional to their temperature in Kelvin.

Question 9

Kinetic Theory of Gases
3rd

Answer 9

The distance between gas particles are so large relative to the volume of the gas particles, that we say that gas particles don’t have a volume. They are called point masses

Question 10

Kinetic Theory of Gases
5th

Answer 10

There are no forces of attraction or repulsion between gas particles

Question 11

Volatile

Answer 11

Evaporates easier

Question 12

Relative molecular mass

Answer 12

Mass of 1 mole
