Question

Determine the mass and weight of the air in your living room at 20°C ; the room has the following dimensions ;4m ×5m floor and ceiling is at 3m height. Take the density of the air as ​

Answer 1

Volume of air is
`60` cubic meter

Mass of air is
`72.246` Kilogram

Step-by-step explanation:

As air occupies the volume of the container in which it is kept. The volume of air here in this case will be equal to the volume of the room.

Volume of the room = length * breadth * height

Volume of the room =
`4*5*3 = 60` cubic meter.

Volume of air is also
`60` cubic meter.

Density of air at 20 degrees C
`= 1.2041` kg/cu.m

Mass of air

Volume * density

`60 * 1.2041 = 72.246` kilogram

Volume of air is
`60` cubic meter

Mass of air is
`72.246` Kilogram
