How does the anomalous expansion of water help aquatic organisms in cold climates?
A calorimeter contains 50 g of water at 50°C. The temperature falls to 45°C in 10 minutes. When the calorimeter contains 100 g of water at 50°C, it takes 18 minutes for the temperature to become 45°C. Find the water equivalent of the calorimeter.
Draw a graph between volume and temperature, when 5 cm3 of ice at -10°C is heated to form water at +10°C.
A deep pond of water has its top layer frozen. What will be the likely temperature of water layer just in contact with ice?
In cold countries, the water pipes are covered with poor conductors. Why?
The following diagrams illustrate three situations involving thermometers which are labeled A, Band C. In each situation the thermometers indicate different readings.
(i) What do you expect the approximate reading of the thermometer B and C would be? Give a reason for your answer.
(ii) How would the readings of A and B help you in calibrating a thermometer?
