Answer 2

Seawater will have the maximum density at room temperature (option C)

• Water has a more compact arrangement of molecules than oils and other organic solvents. So, its density is higher.
• At room temperature, the density of water is 1g/l,  olive oil is 0.917 g/l and that of acetone is 0.788g/l.

• Seawater has dissolved salts, therefore, its density is greater as compared to pure water.
• Note that oils expand on heating and their density decreases.
