Mole/Properties of Gases

Question 1

One mole

Answer 1

amount of that substance which contains Avogadro’s number of particles.

Question 2

Gas

Answer 2

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

Question 3

Boyle’s law

Answer 3

pressure inversely proportional to volume for definite mass of gas at constant temperature.

Question 4

Charles’ law

Answer 4

volume of a fixed mass of gas at constant pressure is proportional to temperature in kelvins.

Question 5

Gay-Lussac’s Law of Combining Volumes

Answer 5

the volumes measured at the same temperature and pressure of reacting gases and their gaseous products are in small whole number ratios.

Question 6

Avogadro’s law

Answer 6

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

Question 7

Ideal gas

Answer 7

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

Question 8

How real gases differ from ideal gases? 2 ways.

Answer 8

i) forces of attraction and repulsion do exist between the particles ii) the volume of the particles is not negligible.
