Question

Assume that heat is being supplied continuously to 2kg of ice at -5°C. You know that ice melts at 0°C and boils at 100°C. Continue the heating till it starts boiling. Note the temperature every minute. Draw a graph between temperature and time using the values you get. What do you understand from the graph. Write the conclusions.

Answer 1

Hey.

Here is the answer.

We can see from the graph that at temperature 0℃ and 100℃ the line becomes parallel to time axis but from -5℃ to 0℃ and from 0℃ to 100℃ it is increasing in nature.

From this we can conclude that :

1. for melting at 0 it takes some time to convert all ice to water and no temperature is changed until melting completes

2. for Bolling at 100 it takes time

3. latent heat of vaporisation and fusion are absorbed at 100 and 0 respectively and hence no increase in temperature is seen for some duration.

Thanks.
