				   Iin an experiment to determine the latent heat of vapourisation of water, a student boils some water in a beaker using a electric heater THEN (1)THERMAL ENERGY IS LOST FROM THE SIDES OF THE BEAKER AND (2)AS THE WATER IS BOILING,WATER SPLASHES OUT OF THE BEAKER WHICH OF THEM WOULD INCREASE AND DECREASE AND WHY?

Answers : (1)



Latent heat of vaporization is the quantity of heat energy required to transform 1 kg of water at its boiling point 100 Celsius completely into gas is known as latent heat of vaporization. During boiling the temperature of water remains constant at 100 Celsius although heat is being constantly supplied to it. Thermometer therefore does not register any increase in temperature above 100 Celsius. All the additional heat energy supplied to the boiling water at 100 Celsius is utilized to transform the liquid state water into gaseous state.
