Gas with a volume of

`3m^(3)`

at a pressure of 1 Calculate: a) The final volume if the temperature increases from

`22\deg C`

to

`165\deg C`

. b) The final volume if the temperature is kept constant. Air is compressed in a cylinder from a pressure of 80 kPa and a temperature of

`25\deg C`

so that the volume occupies one quarter of the original volume while the temperature remain constant. Calculate: a) The final pressure of the air. b) The final temperature if the air is now heated to the original volume at the new pressure.
