Question

A student inhales to fill her lungs with air, thereby slightly increasing the volume of her body. What effect does this have on the density of her body?

Liquid mercury has a density much greater than that of water. If equal volumes of mercury and water are measured, how will their masses compare?

a. it does not affect the density b. the volume of air inhaled is needed to determine the answer c. it increases the density d. the mass of her body is needed to determine the answer e. it decreases the density

Liquid mercury has a density much greater than that of water. If equal volumes of mercury and water are measured, how will their masses compare?

a. the density of mercury and water are needed to determine the answer b. the mass of the mercury will be less than the mass of the water c. the volume of mercury and water measured is needed to determine the answer d. the mass of the mercury will be equal to the mass of the water e. the mass of the mercury will be greater than the mass of the water

Explanation / Answer

Density = Mass / Volume

1 (e) it decreases the density

2 (e) the mass of the mercury will be greater than the mass of the water
