The following line graph shows the change in temperature of a block of ice when heated.
Study the above graph carefully and answer the questions given below:
(i) For how many seconds did the ice block have no change in temperature?
(ii) For how long was there a change in temperature?
(iii) After how many seconds of heating did the temperature become constant at 100° C?
(iv)What was the temperature after 25 seconds?
(v) What will be the temperature after 1.5 minutes? Justify your answer.
(i) The ice block had no change for 20 seconds.
(ii) There was a change in the ttemperature for 30 seconds
(iii) After 50 second, the temperture became constant at 1000 c.
(iv) The temperature after 25 second was 180 c.
(v) The temperature after 1.5 min will be 1000 c as it is uniform after 50 seconds.
