gas laws

Question 1

gas

Answer 1

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

Question 2

temperature

Answer 2

measure of degree of hotness of an object

Question 3

pressure of gas

Answer 3

the force the gas exterts on a unit of area of its container

Question 4

boyles law

Answer 4

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

Question 5

charles law

Answer 5

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

Question 6

gay lussacs law of combining gases

Answer 6

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 7

avagadros law

Answer 7

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

Question 8

real gas

Answer 8

a real gas differs from ideal gases because forces of attraction and repulsion do exist between the molecules and the volume of the molecules is not negligible

Question 9

ideal gas

Answer 9

one that perfectly obeys all the assumptions of the kinetic theory of gases under all conditions of temperatures and pressure
