Fluids. Density of Fluids Revision Questions
1. A massless container filled with 4.2 kg water up to 70% of its volume is shown in the figure.
Water is replaced by another liquid with density 1.2 g/cm3 which fills up the entire container as shown in the second figure. Calculate the mass of the unknown liquid.
Take the density of water equal to 1 g/cm3.
- 7.2 kg
- 6.0 kg
- 5.0 kg
- 3.5 kg
Correct Answer: A
2. What is the density of mixture if we mix 96 g alcohol and 96 g of glycerine in the same vessel?
Take ρalcohol = 0.8 g/cm3 and ρglycerine = 1.2 g/cm3
- 1.0 g/cm3
- 1000 g/cm3
- 0.96 g/cm3
- 0.98 g/cm3
Correct Answer: C
3. Why an empty balloon cannot fly and when filled with helium it flies up in air?
- Because helium helps the balloon become lighter
- Because helium has a negative mass
- Because the volume inside the balloon increases more than mass and thus the density decreases
- Because both volume and mass inside the balloon increase at the same rate bringing an increase in density
Correct Answer: C
