Question
Calculate the mass of air enclosed in a room of length, breadth and height equal to 5m, 4m and 2m respectively. (Consider density of air 1.3 kg/m2)A 78 kg B 0.032 kg C 1.3 kg D 52 kg
Solution
To calculate the mass of air enclosed in a room, we need to use the formula:
Mass = Density * Volume
Given:
- Density of air = 1.3 kg/m^3
- Dimensions of the room = 5m * 4m * 2m
First, calculate the volume of the room:
Volume = Length * Breadth * Height Volume = 5m * 4m * 2m = 40 m^3
Then, substitute the values into the formula:
Mass = Density * Volume Mass = 1.3 kg/m^3 * 40 m^3 = 52 kg
So, the mass of the air enclosed in the room is 52 kg. Therefore, the correct answer is D. 52 kg.
