Density:
- The density of a substance is its mass per unit volume.
- It means that density is inversely proportional to volume.
- The SI unit of the density is kg/m3.
The graph between the specific volume and temperature of water:
- The volume of a given amount of water decreases between 0°C to 4°C.
- The volume starts to decrease when water is heated from 0°C because the heating causes the density of water to increase.
Explanation:
- Though liquids expand on heating, water does not expand between 0°C to 4°C instead it contracts as water has maximum density at 4°C.
- It expands above 4°C.
- Hence, the volume of a given amount of water decreases when its temperature is increased from 0°C to 4°C.
