Final answer:
The mass of the air inside a typical house with a floor area of 150 m² and a floor-to-ceiling height of 2.5 m is 459.375 kg. This would be too heavy to lift if it were in the form of bags of rocks, which exceeds the average lifting capacity of a person.
Step-by-step explanation:
The question is asking for the mass of air inside a typical house with specific floor area and floor-to-ceiling height. To calculate the mass of the air, we need to know the volume of the space and the density of air. With a floor area of 150 m² and a floor-to-ceiling height of 2.5 m, the volume of the air inside the house would be 375 m³ (150 m² * 2.5 m). The density of air at standard conditions is approximately 1.225 kg/m³. Multiplying the volume by the density gives the mass: 375 m³ * 1.225 kg/m³ = 459.375 kg.
Considering that the average person can lift a maximum of about 25 kg at a time, one could not lift the entire mass of air if it were condensed into bags of rocks. However, air is obviously not solid like rocks, and its mass is spread across the entire house, making this a theoretical exercise rather than a practical one.
