When the temperature of water rises from `0^(@)C` to `10^(@)C`,the density of water
A
decreases gradually.
B
decreases up to `4^(@)C` and then increases.
C
increases up to `4^(@)C` and then decreases.
D
increases gradually.
Text Solution
Verified by Experts
The correct Answer is:
C
Density of water is maximum at `4^(@)C` du to anomalous expansion of water. Hence, when the temperature of water is raised from `0^(@)C` to `10^(@)C`, the density increases up to `4^(@)C`, then decreases gradually.
When water is heated from 0^(@)C to 10^(@)C , the volume of water
A block of wood is floating on water at 0^(@)C with volume V_(0) above water. When the temperature of water increases from 0 to 10^(@)C , the change in the volume of the block That is above water is best described schematically by the graph
If the temperature of water is raised from 0 ""^(@)C to 10^(@)C , its volume goes on increasing .
If the temperature of water is decreased from 4^(@)C from 10^(@)C ,then its "…..............." .
When water is heated from 0^(@)C to 10^(@)C , its volume
When the temperature of water rises, the rate of evaporation
