1. Which has the greater density—1 kg of water or 10 kg of water?

Question

2. Which has the greater density—5 kg of lead or 10 kg of aluminum?

3. Which has the greater density—an entire candy bar or half a candy bar?

Accepted Answer

1. The density of any amount of water is the same: 1 g/cm^3 or, equivalently, 1000 kg/m^3, which means that the mass of water that would exactly fill a thimble of volume 1 cubic centimeter would be 1 gram; or the mass of water that would fill a 1-cubic meter tank would be 1000 kg. One kg of water would fill a tank only a thousandth as large, 1 liter, whereas 10 kg would fill a 10-liter tank. Nevertheless, the important concept is that the ratio of mass/volume is the same for any amount of water.

2. Density is a ratio of weight or mass per volume, and this ratio is greater for any amount of lead than for any amount of aluminu —see Table 1.

3. Both the half and the entire candy bar have the same density.
