(a)
Interpretation:
The volume of air is to be calculated when pressure and temperature of the gas are given at two conditions.
Concept introduction:
Ideal gas equation helps to calculate volume of a gas at given temperature and pressure. According to this law,
Where
Answer to Problem 98A
The volume of one breath is
Explanation of Solution
Ideal gas equation helps to calculate volume of a gas at given temperature and pressure. According to this law,
Or
Given data is:
Now substituting the values into formula,
Therefore volume of air is
(b)
Interpretation:
If percentage of oxygen is 14 % then what volume of air need to breathe by human?
Concept introduction:
Percentage calculations will help to solve the problem. More volume of air is to breathe at height to supply the body with same amount of oxygen.
(b)
