A vertical glass jar is filled with wate...

A vertical glass jar is filled with water at `10^(@)C`. It has one thermometer at the top and another at the bottom. The central region of the jar is grdually cooled. It is found that the bottom thermometer reads `4^(@)C` earlier than the top thermometer. And the top thermometer reads `0^(@)C`. earlier than the bottom thermometer. This happens because

A

The top thermometer is faulty

B

The bottom thermometer is faullty

C

Density of water is maximum at `4^(@)C`

D

Density of water is minimum at `0^(@)C`

At the top of a mountain, the thermometer reads 0^(@)C and the barometer reads 700 mm Hg . At the bottom of the mountain the thermometer reads 30^(@)C and the pressure 760 mm Hg. Compare the density of the air at the top with that at the bottom

Two thermometers A and B are calibrated in differ ent scales. When both the thermometers are placed in a container filled with hot water the mercury thread in the thermometer A has moved through divisions whereas the mercury thread in thermometer B has moved though 15 divisions. The reading on thermometers A and B are 20^(@)C and 40^(@) respectively. If the lower fixed point of the thermometer A is 0^(@) , determine the lower fixed point of the thermometer B.
