properties of gases

Question 1

gas

Answer 1

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

Question 2

temperature can be converted from Celsius

Answer 2

to kelvin by adding 273

Question 3

normal atmospheric pressure/standard pressure

Answer 3

1x10 ⁵ Pa = 100kPa

Question 4

Boyles law

Answer 4

at a constant temperature, the volume of a fixed mass is inversely proportional to its pressure (PV=k)

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 volume

Answer 6

in a reaction between gases, the volumes o 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

avogadros law

Answer 7

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

Question 8

ideal gases

Answer 8

gases that obey all gas laws under alll conditions of temperature and pressure

Question 9

real gases

Answer 9

they do not follow gas laws due to forces of attraction or repulsion between molecules and the volume if the molecules is not negligible
