In an experiment to determine the boiling point of water state the reason for the following recautions:
(i) The bulb of the thermometer should not touch the sides of the beaker.
(ii) while boiling water pumice stone should be added.

During the determination of the boiling point of water the thermometer is kept

What is the boiling point of water at (i) higher altitudes, (ii) in pressure cooker ?

Why a clinical thermometer should not be sterilized by boiling water?

Give the reasons for the following statement: the high boiling point of water is advantageous to living organisms.

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?
