Study of anomalous behaviour of
water using Hope's apparatus
द डेंसिटी ऑफ वॉटर इज ​

Answer 1

Answer:

The anamolous behavior of water can be studied with hope apratous. In hope apratous, a flat bowl is attached to a cylindrical container. There is provision to attach thermometer above (to measure temperature T2) and below (to measure temperature T1) the flat bowl on the cylindrical container and a mixture of ice and salt is put in the flat bowl.

Initially, the temperature of water in the middle of cylinder lower due to freezing mixture in the outer bowl. Since the temperature of water there decreases, its volume decreases, and its density moves downward. Therefore, the lower thermometer T1 shows rapid fall in temperature of water becomes equal to 4degree c. When the temperature of water starts decreasing below 4degree c, its, therefore, moves in the upward direction. The temperature of water in upper part (T2), therefore, decreases rapidly to 0 degrees c. The temperature of water in the lower part (T1), however remains at 4degree c for same time and then decrease slowly to 0 degrees C.
