प्रश्न
A student heats a beaker containing ice and water. He measures the temperature of the content of the beaker as a function of time. Which of the following (Fig. 1.1) would correctly represent the result? Justify your choice.
पर्याय
उत्तर
Since ice and water are in equilibrium, the temperature would be zero. When we heat the mixture, ‘energy supplied is utilised in melting the ice and the temperature does not change till the ice melts because of latent heat of fusion. On further heating the temperature of the water would increase. Therefore (d) is the correct option.
