Gas Laws

Gases are often formed as a product of or are used as a reactant in a

chemical reaction. These materials (gases) have some special properties

and are subject to some special calculations in chemistry. Gases (think of

air as an example) are very light, are easily expandable, are easily

compressible, and completely fill a container into which they are

released. These properties are due to the fact that the individual molecules

of the gas are very far apart from one another, are not...

Show the calculation of the new temperature of a gas sample which has an original volume of 700 ml

when collected at 730 mm and 35oC when the volume becomes 480 ml at 1.15 atm.

700ml/1000= 0.7 liters= Vi

730mm/700= 1.042 atm=Pi

35 ºC + 273 = 308K = Ti
