Water in a cup can have a higher temperature than a bucket of water, although cup has less amount of water.

Water in a cup and a kettle can have the same temperature, even though their quantities are different

A : pH of water termperature dependent. R : Boiling water has pH less than 7.

''A black dot on as a porcelain cup apppears dark. But when heated to a high temperature it becomes brighter than the rest of the cup.'' Why ?

Assertion : Water kept in an open vessel will quickly evaporate on the surface of the moon. Reason : The temperature at the surface of the moon is much higher than boiling point of the water.

A conical paper cup 20 cm across the top and 15 cm deep is full of water. The cup springs a leak at the bottom and losses water at 5 cu. cm per minute. The amount of water (in cm^(3)) when the hight of water is 3 cm is

Luciano measured the amount of water that evaporated over a period of time from a container holding w ounces of water, where w is greater than 12. By the end of the first day, the cub had lost 2 ounces of water. By the end of the 7th day, the cup had lost an additional 8 ounces of water. By the end of the 11th day, the cup had lost half of the water that remained after the 7th day. Which of the following represents the remaining amount of water, in ounces, in Luciano's container at the end of the 11th day?

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

Rate of transpiration higher than rate of water absorption shall cause

Water potential of pure water at standard temperature is equal to
