A beaker containing 20 g sugar in 100 g water and another containing 10 g sugar in 100 g water are placed under a bell- jar and allowed to stand until equilibrium is reached. How much water will be transferred from one beaker to another ?

How much heat is required for 40g water to boil and turn into vapour?

15 g of a solute in 100 g water makes a solution freeze at -1^@C . 30 g of a solute in 100 g of water will give a depression in freezing point equal to :

The water equivalent of a calorimeter is 10g and it contains 50 g of water at 15^(@)C . Some amount of ice, initially at -10^(@)C is dropped in it and half of the ice melts till equilibrium is reached. What was the initial amount of ice that was dropped (when specific heat of ice =0.5"cal"gm^(-1)""^(@)C^(-1) specific heat of water =1.0"cal"gm^(-1)""^(@)C^(-1) and laten heat of melting of ice =80"cal"gm^(-1) )?

How much positive and negative charge is there in a cup of water ? Given mass of one cup of water = 250 g

100 g of water is added to a 100 cc solution of sugar of density 1.5 g/cc. what is the density of the new mixture?

Two calorimeters of water equivalent 25 g and 60 g are initially at 0^(@)C . Some water at 50^(@)C is poured in the first calorimeter and after thermal equilibrium is attained, the first calorimeter is emptied into the second one. If the final temperature of water and the second calorimeter becomes 25^(@)C , find the mass of water.

The mass of a copper steam boiler is 200 kg. It contains 100 kg of water at 25^(@)C.7xx10^(6) cal of heat is produced by burning 1 kg of coal and only 3% of it is absorbed by the boiler to heat water. How much coal is to be burnt to raise the temperature of the water in the boiler to its boiling point? Specific heat of copper ="0.09 cal.g"^(-1).^(@)C^(-1) .
