Equal volumes of the two different substances have equal masses.
Mass = density x .........
Match the following :
| Column A | Column B | ||
| (a) | kg `m^-3` | (i) | relative density |
| (b) | no unit | (ii) | sinks in alcohol |
| (c) | relative density | (iii) | floats on water |
| (d) | iron | (iv) | density |
| (e) | wood | (v) | density bottle |
A density bottle has a marking 25 ml on it. It means that:
It is easier to swim in sea water than in river water. Explain the reason.
The density of aluminium is 2.7 g cm3. Express it in kg m−3.
The density of alcohol is 600 kg m-3. Express it in g Cm-3.
A piece of zinc of mass 438.6 g has a volume of 86 cm3. Calculate the density of zinc.
From the following observations, calculate the density and relative density of a brine solution.
Mass of empty density bottle = 22 g
Mass of bottle + water = 50 g
Mass of bottle + brine solution = 54 g
The mass of an empty density bottle is 30 g, it is 75 g when filled completely with water and 65 g when filled completely with a liquid. Find density of liquid.
