Calculate the molal elevation constant , "K"_("b") for water and the boiling point of 0.1 molal urea solution. Latent heat of vaporisation of water is 9.72 kcal "mol"^(-1) at 373.15K.

Is it possible that water evaporates from a spherical drop of water just by means of surface energy supplying the necessary latent heat of vaporisation? The drop does not use its internal thermal energy and does not receive any heat from outside. It is known that water drops of size less than 10^(–6) m do not exist. Latent heat of vaporisation of water is L = 2.3 × 10^(6) Jkg^(–1) and surface tension is T = 0.07 Nm^(–1) .

As part of an experiment to determine the latent heat of vaporisation of water, a student boils some water in a beaker using an electric heater as shown below. The student notes two sources of error. Error-1: thermal energy is lost from the sides of the beaker Error -2: As the water is boling water splashes out of the beaker Which of the following gives the correct effect of these two errors on the calculated value for the specific lalent heat?
