Density of water is .......Kg m-3.
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:
Icebergs floating on sea water are dangerous for ships. Explain the reason.
A piece of wood of mass 150 g has a volume of 200 Cm3. Find the density of wood in C.GS. unit and S.I. unit.
Calculate the volume of wood of mass 6000 kg if the density of wood is 0.8 g Cm-3
The mass of an empty density bottle is 21.8 g when filled completely with water is 41.8 g and when filled completely with liquid it is 40.6 g. Find
- the volume of density bottle.
- the relative density of liquid.
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.
