Properties Of Gases

Question 1

Gas

Answer 1

Substance that has no well-defined boundaries but diffuses rapidly to fill any container in which it is placed

Question 2

Boyles law

Answer 2

States that, at constant temperature, the volume of a fixed mass of gas is inversely proportional to its pressure

Question 3

Charles’ law

Answer 3

States that, at constant pressure, the volume od a fixed mass of gas is directly proportional to its temperature measured on the kelvin scale

Question 4

Gay-lussacs law of combining volume

Answer 4

In a reaction between gases, the volumes of the reacting gases and the volumes of any gaseous products are in the ratio of small whole numbers provided the volumes are measured at the same temperature and pressure

Question 5

Avogadros law

Answer 5

States that equal volumes of gases contain equal numbers of molecules under the same conditions of temperature and pressure

Question 6

Ideal gas

Answer 6

One that perfectly obeys all the assumptions of the kinetic theory of gases under all conditions of temperature and pressure

Question 7

How do real gases differ from ideal gases

Answer 7

1. Forces of attraction and repulsion do exist between the molecules of real gases
2. The volume of real gases is not negligible
