Question

explain an amorous behaviour of water by using hopes apparatus

Answer 1

Anomalous behaviour of water.
1) Generally substance expand on heating and contract on cooling.
2) Water however shows an exceptional behaviour between the temperature range of 4°C and 0°C.
3) Water when cooled to 4°C expands instead of contracting and this contraction continues to 0°C.
4) This is called as anomalous behaviour of water.

Answer 2

There are five steps to study the anomalous behavior of water by using Hope's apparatus. They are,

• A beaker filled with water is cooled along with the Hope's device an hour before conducting the experiment.

• A cooling mixture is prepared using crushed ice and kitchen salt.

• The Hope's device is isolated and two thermometers are inserted into the two holes of the apparatus respectively.

• Pre-cooled water is filled in the inner cylinder and the outer cylinder is filled with the cooling mixture.

• The temperatures are observed using the thermometers.
