The reason for using ethyl chloride (a spray that evaporates quickly) during a game to numb a sports injury should be explained. Concept Introduction: Evaporation is the process of converting water (mostly) in liquid state to the gaseous state. Due to change in state of water from liquid to gas its temperature increases and energy is required for such change in state, Thus the water molecules undergoing evaporation, decreases the temperature of the surface by absorbing the heat energy from it.

(8) 9. How much energy is required to heat 81.0 g of water (specific heat = 1.00 cal/g °C) at 11.0°C to steam (specific heat 0.468 cal/g°C) at 123.0°C? (Heat of vaporization of water = 540. cal/g)

does it compare with the known melting and boiling point? (1) 9. The average kinetic energy of water molecules is a measure of the temperature of water. When the temperature of water remains constant the average kinetic energy of the molecules remains constant, even though the water is being heated by the Bunsen flame. So, energy is being taken in by the water, but it is not being used to increase the kinetic energy of the molecules. 9.1 What type of energy are the water molecules gaining during a phase change? (1) 9.2 Explain your reasoning (to question 9.1) with reference to the kinetic theory of matter. 10. Write the conclusion. (3) [30]

What mass of liquid water at room temperature (25°C) can be raised to its boiling point with the addition of 24 kJ of energy? (77g)
