(a)
To Find: The total mass of air.
(a)
Answer to Problem 82GP
The total mass of air inside the house at 20 0C is
Explanation of Solution
Given:
Volume of house
The density of air
Temperature
Coefficient of thermal expansion of air
Formula used:
The total mass of air inside the house is the difference between the mass of air at 0 0C and mass of air at 20 0C. The following formula will be helpful t find the total mass of air inside the house.
Mass of air inside the house
Density
Mass
.Calculation:
Substitute the given values,
mass at
Mass at
The total mass of air inside the house =
Conclusion:
Thus, the total mass of air inside the house at
(b)
To Find: The total mass of air when the temperature decreases.
(b)
Answer to Problem 82GP
The total mass of air enters the house and the mass of air when the temperature decreases to -10 0C are
Explanation of Solution
Given:
Formula used:
Find the total mass of air when temperature decreases to -10 0C by the following way,
Calculation:
Substitute the given values,
At -10 0C, the mass of air is
Conclusion:
Thus, the total mass of air enters the house, and the mass of air when the temperature decreases to -10 0C are
