➽ i) The anomalous behaviour of water can be studied with hope’s apparatus.
➽ ii) In Hope's apparatus, there is a metallic cylindrical container. At the middle of the cylinder, there is a flat bowl.
➽ iii) Two thermometer one at the upper region and other at the lower region is fixed to record the temperature.
➽ iv) The freezing mixture of salt and ice is taken in the flat bowl. Temperatures are recorded after every 30 minutes.
➽ v) Water of 10 degree Celsius is poured into the cylindrical container. Initially, both the thermometer to show the temperature of 10 degree Celsius.
➽ vi) As the temperature of water decreases due to freezing mixture, it contracts, density increases and goes to the bottom of the container till 4 degree Celsius.
➽ vii) Due to this, for sometime the thermometer at the bottom shows temperature of 4 degree Celsius.
➽ viii) As the temperature falls below 4° Celsius, water in the region expands instead of contracting, density decreases and this water rises towards the surface.
➽ ix) After sometime, the upper thermometer shows the temperature of 0 degree Celsius and lower thermometer shows 4 degree Celsius.
➽ x) Finally both thermometer shows 0 degree Celsius.
➽ xi) In this way, the anomalous of behaviour of water can be demonstrated in the laboratory by using hope's apparatus.
