Question

If you change the mass and volume does the density of a fluid changes?

Solve: 1. D= 1000kg÷ 4m^3

2. D= 1000kg÷ 2m^3

3. D= 600kg÷ 3m^3

4. D= 400kg÷ 3m^3

Answer 1

If you change the mass and volume, the density of a fluid changes, although it depends on the way you change the mass and volume.

$1. D= 1000\text{ kg}÷ 4\text{ m}^3=250\text{ kg/m}^3,\\ 2. D= 1000\text{ kg}÷ 2\text{ m}^3=500\text{ kg/m}^3,\\ 3. D= 600\text{ kg}÷ 3\text{ m}^3=200\text{ kg/m}^3,\\ 4. D= 400\text{ kg}÷ 3\text{ m}^3=133\text{ kg/m}^3.$
