When heat is constantly supplied by a gas burner with a small flame to melt ice, then the temperature of ice during melting :
(a) increases very slowly (b) does not increase at all
(c) first remains constant and then increases (d) increases to form liquid water

(c) first remains constant and then increases (d) increases to form liquid water
Answer: (b) does not increase at all
The temperature at which pure ice melts to form water is called the melting point of ice The temperature remains constant throughout the melting of ice. However, this energy is used to convert water whose physical state is solid to a loquid state which is water. The usage of this stired energy is called latent heat of fusion the melting point of pure ice is 0° Celsius at a pressure of 76 cm mercury. Note that the temperature does not rise as all available heat energy is used to increase the kinetic energy of the water molecules so that it obtains an intra molcular space comparable to liquid water at the same temperature.
