Gas Laws

Question 1

What is Boyle’s law?

Answer 1

When temperature is constant, volume is inversely proportional to pressure

Question 2

What’s Charle’s law?

Answer 2

When pressure in constant, volume is proportional to temperature

Question 3

What is Avogadro’s law?

Answer 3

When temperature and pressure are constant, equal volumes of gases contain equal numbers of particles

Question 4

What is Gay-Lussac’s law?

Answer 4

When gases react, the volume of reactants and products are in a simple, whole number ratio, under the same temperature and pressure.

Question 5

What is a mole?

Answer 5

A mole of any substance is defined as the amount of substance that contains as many particles as there are atoms of carbon-12 in 12g of carbon-12.

Question 6

What is an ideal gas?

Answer 6

An ideal gas obeys the kinetic theory at all temperatures and pressures

Question 7

What is a volatile liquid?

Answer 7

Liquid that vaporises at low temperatures

Question 8

What is the kinetic theory of gases?

Answer 8

1) Gases made of particles in constant motion
2) No attraction/repulsive forces between molecules
3) Size of molecules is negligible
4) Collisions between molecules are elastic
5) Average kinetic energy is proportional to temperature

Question 9

What are the problems with the kinetic theory?

Answer 9

1) There are intermolecular forces
2) Particles have a definite size
3) collisions between particles are not elastic
