Question

Density is the mass of any material per unit volume. Gases always have much lower density than the condensed phase. Density depends on temperature and pressure. For solids, it’s also affected by the way atoms and molecules stack together. A pure substance can take many forms, which don’t have the same properties. For example, carbon can take the form of graphite or diamond. Both are chemically identical, but they do not share an identical density value.
1According to information provided above, on decreasing the temperature, the density of the same mass of the liquid increases. Explain what happens when the temperature of water is decreased?
2Arrange the following in increasing order of their densities-
smoke, honey, alcohol, wood, cotton, sea water,

Answer 1

Answer:

Ans 1) When the temperature of water is decreased,the density of it increases which leads to trapping of fewer water molecules.

Ans 2) The order is smoke, alcohol, cotton, honey , sea water, wood
