Answer 2

Calculation of Air Volume:

To determine the volume of air that passed through the boy's lungs, we need to use the ideal gas law, which states that the volume of a gas is directly proportional to its mass, temperature, and pressure. However, since the question specifies that we need to calculate the volume at normal pressure and temperature, we can assume that the pressure and temperature are constant.

The ideal gas law equation is as follows: PV = nRT

Where: - P is the pressure of the gas - V is the volume of the gas - n is the number of moles of the gas - R is the ideal gas constant - T is the temperature of the gas

Since we are given the mass of the air (14.7 kg) and want to find the volume, we need to rearrange the equation to solve for V: V = (m/M) * (RT/P)

Where: - m is the mass of the gas - M is the molar mass of the gas

In this case, the gas is air, which is a mixture of different gases. The molar mass of air is approximately 28.97 g/mol.

Now, let's calculate the volume of air that passed through the boy's lungs.

Given: - Mass of air = 14.7 kg - Molar mass of air = 28.97 g/mol

Using the equation above, we can calculate the volume of air: V = (14.7 kg / 0.02897 kg/mol) * (8.314 J/(mol·K) * 298 K / 1 atm)

Calculating this expression gives us the volume of air that passed through the boy's lungs.

Calculation of Room Volume:

To compare the volume of air that passed through the boy's lungs with the volume of air in the room, we need to calculate the volume of the room.

Given: - Width of the room = 4 m - Length of the room = 5 m - Height of the room = 2.8 m

The volume of the room can be calculated by multiplying these dimensions together: Volume of the room = Width * Length * Height

Substituting the given values into the equation, we can calculate the volume of the room.

Comparison of Air Volumes:

Once we have calculated the volume of air that passed through the boy's lungs and the volume of the room, we can compare the two volumes to see how they relate to each other.

Let's assume we have calculated the volume of air that passed through the boy's lungs as V1 and the volume of the room as V2.

To compare the volumes, we can calculate the ratio of V1 to V2: Ratio = V1 / V2

This ratio will give us an indication of how much of the room's volume the air that passed through the boy's lungs occupies.

Please note that the actual values for the volume of air and the volume of the room will depend on the calculations performed using the given values.
