Question

5. In the above experiment, the point of intersection of the two curves in
the graph corresponds to the
(A) melting point of ice
(B) freezing point of water
(C) temperature at which the density of water is minimum
(D) temperature at which the density of water is maximum​

Answer 1

Explanation:

a) 170 °C

b) 0 °C

c) 0°C

0°CWater density changes with temperature and salinity. Density is measured as mass (g) per unit of volume (cm³). Water is densest at 3.98°C and is least dense at 0°C (freezing point).

d) 4oC

4oCAt 4oC, the density of water is maximum. Its value is 1000 kgm−3.
