Two beakers are filled with water. One is cooled and the other is heated. Water is found overflowing in both. The temperature of water must be

when water is cooled , it changes to ice . Why

The pH of neutral water is 6.5 , then the temperature of water is

Water vasuclar system is found in

When the water in a beaker is heated the warm water

The total energy radiated from a block body source at constant temperature is collected for one minute and is used to heat a quantity of water. The temperature of water is found to increase from 20^(@)C to 20.5^(@)C . If the absolute temperature of the blackbody is doubled and the experiment is repeated with the same quantity of water of 20^(@)C , the temperature of water will be:

A beaker filled with water, is accelerated at a rate a m/s^(2) in forward direction. The surface of water shall make an angle

A and B are two separate reservoirs of water. Capacity of reservoir A is double the capacity of reservoir Bdot Both the reservoirs are filled completely with water, their inlets are closed and then the water is released simultaneously from both the reservoirs. The rate of flow of water out of each reservoir at any instant of time is proportional to the quantity of water in the reservoir at the time. One hour after the water is released, the quantity of water is reservoir A is 1 1/2 times the quantity of water in reservoir Bdot After how many hours do both the reservoirs have the same quantity of water?

A uniform capillary tube of inner radius r is dipped vertically into a beaker filled with water. The water rises to a height h in the capillary tube above the water surface in the beaker. The surface tension of water is sigma . The angle of contact between water and the wall of the capillary tube is theta . Ignore the mass of water in the meniscus. Which of the following statements is (are) true?

Two containers A and B are partly filled with water and closed. The volume of A is twice that of B and it contains half the amount of water in B. If both are at the same temperature, the water vapour in the containers will have pressure in the ratio of

A beaker is completely filled with water at 4^(@)C. It will overflow if
