Question

need and importance of hope's appartus​

Answer 1

Answer: Importance

Explanation:

It is a common experience that when a liquid is heated, it expands, irrespective of the temperature range. However, water is an exception. When water at 0 ºC is heated, it contracts till 4 ºC, instead of expanding. On further heating from 4 ºC, water expands like other liquids do. The special behaviour of water between 0ºC and 4ºC is called the anomalous behaviour of water.

In the year 1805, the scientist T. C. Hope devised a simple arrangement, known as Hope’s apparatus, to demonstrate the anomalous behaviour of water.
