What do you mean by colligative properties? Boiling point of water at 750mm is 99.63^@C . How much sucrose is to be added to 500gm of water so that it boils at 100^@C (given k_b = 0.52 )

The boiling point of water in Kelvin scale is—

How much heat 50 gm of water at 25^@C will take to reach boiling point?

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

The solubility of a specific non-volatile salt is 4 g in 100 g of water at 25^@C . If 2.0 g, 4.0 g and 6.0 g of the salt added to 100 g of water at 25^@C , in system X, Y and Z. The vapour pressure would be in the order :

Boiling point of H_(2)O_(2) is _____ than 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) .
