Question
How to study the anomalous behavior of water by using Hopes Apparatus?
Open in App
Solution
There are five steps to study anomalous behavior of water by using Hope's Apparatus.1. A beaker filled with water is cooled along with Hope's device an hour before conducting the experiment..2. A cooling mixture is prepared using crushed ice and kitchen salt.3. Two thermometers are fitted, one at high top and one at lower part.4. At starting both the thermometer show same temperature. After the time progresses the temperature reached by the lower thermometer remains constant at 4∘C and other thermometer records continuously falls of temperature up to 0∘C and remains steady.5. The expension of water when cooled from 4∘C to 0∘Cis anomalous expansion of water.
