Observe the following graph. Considering the change in volume of water as its temperature is raised from 0°C, discuss the difference in the behaviour of water and other substances. What is this behaviour of water called?
Consider the situation of the previous problem. Assume that the temperature of the water at the bottom of the lake remains constant at 4°C as the ice forms on the surface (the heat required to maintain the temperature of the bottom layer may come from the bed of the lake). The depth of the lake is 1.0 m. Show that the thickness of the ice formed attains a steady state maximum value. Find this value. The thermal conductivity of water = 0.50 W m−1°C−1. Take other relevant data from the previous problem.
What do you mean by the anomalous expansion of water?
Explain, why are the exposed water pipes lagged with straw during severe winter?
What are hot spots? How can you extract energy from a hot spot, if it does not come in contact with underground water?
While studying anomalous behaviour of water in Hope’s apparatus, the upper temperature of the thermometer : 0 °C : : lower temperature of the thermometer : _______
Draw a neat and labelled diagram of Hope’s apparatus.
Match the columns:
| Column ‘A’ | Column ‘B’ |
| The density of water is maximum at | (a) 0°C |
| (b) 4°C | |
| (c) 100°C |
