The density of ice is 0.918 g cm-3 and that of water is 1.03 g cm-3 . An iceberg floats with a portion of 224 m3 outside the surface of water. The total volume of ice berg is:
1545 m3
2575 m3
2060 m3
1030 m3
Relative density of a substance is expressed by comparing the density of that substance with the density of

Both (i) and (ii) are false
For what purpose is the acid battery hydrometer used?
To find the density of hydrochloric acid in an acid battery
To find the relative density of sulphuric acid in an acid battery
To find the density of sulphuric acid in an acid battery
To find the relative density of hydrochloric acid in an acid battery
A body of weight W, experiences an upthrust R in water. What will be the apparent weight of the body and apparent density of the body when W<R?
Apparent weight = R - W; Apparent density = (1 - ) g cm-3
Apparent weight = W - R; Apparent density = (1000 - ) kg m-3
Apparent weight = W - R; Apparent density = (-1) g cm-3
Apparent weight = Zero; Apparent density = Zero
A spring balance records a weight of one kgf when a body is suspended from it. When the body is fully immersed ina liquid ,the reading recorded by the spring balance is zero.What is the apparent density of the body ?
0.5 kg m-3
2 kg m-3
0 kg m-3
A substance floats in water, but sinks in coconut oil. The density of the substance
is less than the density of water and equal to the density of oil
is greater than the density of oil and equal to the density of water
is less than the density of water and greater than the density of oil
cannot be decided based on the given information.
Why does ice float on water?
Density of ice and water is same but ice is a solid
Ice does not float on water
Density of ice is higher than that of water
Density of ice is less than that of water
