1. Volume of water displaced = 0.7 cm * 1 cm * 1 cm = 0.7 cm 3 2. Mass of displa

Question

1. Volume of water displaced = 0.7 cm * 1 cm * 1 cm = 0.7 cm3

2. Mass of displaced water = 0.7 cm3 * 1 g/cm3 = 0.7 gm

3. Mass of 0.7 cm3 block is 0.7 gm so mass of 1 cm3 = 1 gm

4. Density of block = 1 gm/cm3

6. Using words rather then numbers, compare the ratio of the volume of the volume of the submerged part of the block (v submerged) to the total volume of the block (v total) with the ratio of the density of the block (block) to the density of the water p(water). The ratio v(submerged)/v(total) is the ___ ratio p(block)/p(water)

Explanation / Answer

1. Volume of water displaced = 0.7 cm * 1 cm * 1 cm = 0.7 cm3

2. Mass of displaced water = 0.7 cm3 * 1 g/cm3 = 0.7 gm

3. 1 cm3 of block displaced 0.7 cm3 of water which had 0.7 gm weight

so

0.7 gm of water is displaced by block so weight of block is 0.7 gm.

4. Density of block = 0.7 gm/cm3

5. p(block)/p(water) = 0.7/1 = 0.7
