Answer 2

Hey there!

1. How does density of a substance change with temperature?

A. As the temperature increases, the density of the substance decreases. As the temperature decreases, density of the substance increases.

That is, Temperature of a substance is directly proportional to the density of the substance.

2. Name the phenomenon due to decrease in the density gases and liquids on heating.

A. Evaporation

3. Ice cubes float in water. Is the relative density of ice <1, =1 or > 1

A. The relative density in comparison with water is 0.916 g/cm³. So, it is <1

4. Name a device that is used for measuring the density / relative density of a liquid.

A. Hydrometer or a
Areometer 

5. At what temperature is the density of water maximuim?

A. 3.98 °C (39.16 °F)

Hope it helps!
