Chapter 2: Problem 99

Using a bathroom scale, a tub, a sponge, and a measuring cup, explain how you would measure your own density.

Short Answer

Expert verified
To measure your own density, first measure your mass in kg using a bathroom scale. Fill a tub with water, mark the initial water level, and submerge yourself fully in it, marking the new water level afterward. Measure the volume of displaced water in liters using a measuring cup. Finally, calculate your density using the formula: Density (ρ) = Mass (m) / Volume (V), where mass is your weight and volume is the displaced water.

Step by step solution

01

Measure your mass

Using the bathroom scale, stand on it and note down your mass (weight) in kilograms (kg). Let's denote your mass as m.
02

Fill the tub with water

Fill the tub with water up to a level where your entire body can be submerged. Ensure that the water level is enough to cover your entire body while lying down, but not too high that water will overflow when you get in.
03

Mark the initial water level

Before submerging yourself in the tub, use a sponge or any other waterproof marker to mark the initial water level on the side of the tub. This initial water level is important to calculate the volume of the water displaced by your body.
04

Submerge yourself in the tub

Carefully get into the tub and submerge yourself completely. Make sure that your entire body is submerged in water. It's best to do this with the help of someone else who can ensure that you are fully submerged. Remember not to touch the marked water level on the tub while submersing yourself.
05

Mark the new water level

After you are fully submerged, the water level in the tub will rise. Have your helper mark the new water level on the side of the tub with the sponge or waterproof marker.
06

Measure the displaced water

Carefully get out of the tub without disturbing the water level. Now, use the measuring cup to measure the exact volume of water between the initial water level and the new water level marked on the tub. This volume of water (V) represents the volume of your body that was submerged into the water. Record the volume of water in liters (L).
07

Calculate your density

Using the mass (m) obtained in Step 1 and the volume (V) obtained in Step 6, we can now calculate your density (ρ) by using the formula: Density (ρ) = Mass (m) / Volume (V) Plug in the values you obtained and calculate your density. The result will be in kg/L or kg/m³ unit. Remember that the accuracy of this method may not be very precise, but it will give you a good approximation of your body's density.
