The atmosphere pressure can support mercury in a tube, which the upper end is closed, up to 0.76 meter. If the mercury is replaced by pure water in this case, what is the maximum height the atmosphere pressure can support the water in such kind a tube? (The density of mercury is about 13.6 times larger than that of water).

Maximum height the atmosphere pressure can support the

water=10.336 m

Explanation:

We know that ,

Case 1 - Mercury in the tube

Case 2 - Water in the tube

Since atmospheric pressure is same

.

or,  

∴

Hence height of the water column =10.336 m

the temperature in kelvin of 2.0 dm3 of an ideal gas is doubled and its pressure is increased by a factor of four. what is the final volume of the gas
