Question

C. Write true or false. Correct the false statements. 1. The density of gases is more than that of solids. 2. The volume of any liquid completely filled in a relative density bottle remains the same. 3. We need to know only the mass of the substance to determine its relative density. 4. Kerosene is lighter than water. 5. The density of a substance is the ratio of its density to the density of water at 4°C. 6. On multiplying the relative density by 1000, one gets the density of a substance in kg/m3. 7. A body of density 3.5 g/cm3 will float on water. 8. The base of the bulb of the hydrometer is filled with lead so that the hydrometer can float in a horizontal position. 9. Convection currents occur due to differences in density in different sections of a liquid or gas. 10. A land breeze arises due to the differential heating between land and water surfaces.
