Gas Laws

Question 1

The law of combining gas volumes

Answer 1

At constant temperature and pressure, the volume of gases in a chemical reaction react in simple whole number ratios

Question 2

The two Avogadro’s law

Answer 2

volume is proportional to mole
1. At the same temperature and pressure, equal volume of gases contain equal number of molecules.
2. The volume of a gas is directly proportional to the number of gas moles at a constant temperature and pressure.
n1/v1=n2/v2

Question 3

Boyle’s law

Answer 3

pressure is inversely proportional to volume
For a given quantity of gas at a constant temperature, the pressure of the gas is inversely proportional to its volume.
P1V1=P2V2

Question 4

Charles law

Answer 4

volume is proportional to temperature
For a given quantity of gas at a constant pressure, the volume of the gas is directly proportional to its temperature.
V1/T1=V2/T2

Question 5

Gay-Lussac’s Law

Answer 5

pressure is proportional to temperature
For a given quantity of gas at a constant volume, the pressure of the gas is directly proportional to its temperature.
P1/T1=P2/T2

Question 6

What is the formula for the ideal gas law

Answer 6

PV = nRT
where R = 8.314
