A room has a dimension of 10m times 10m times 5m. If the specific volume of air in the room is 1.25 m^3/kg, what will be the mass inside? (in kg) 625 400 325 450

Solution

Specific volume is a property of materials, defined as the number of cubic meters occupied by one kilogram of a particular substance. The standard unit is the meter cube per kilogram

given specific volume (V_s) = 1.25 m³/kg

volume of the room (V) = 10*10*5 m³

= 500 m³

Therefore mass inside the room is (m) = V/V_s

= 500/1.25

= 400 kg
