A rectangular room has dimensions,

length 3.5m ; width 4.5m ; height 3.25m

A mercury barometer in the room shows a pressure equal to a height of column of mercury of 760mm and a thermometer in the room shows a temperature of 18oC.

Density of mercury = 13550 kg/m3 Gas constant for air, Rair = 287 J/kg K

Acceleration due to gravity = 9.807 m/s2

a) What is the air pressure in the room ? kPa

b) What is the temperature of the air in the room ? K

c) What is the density of the air in the room ? kg/m3

d) What is the mass of air in the room ? kg
