Question
A student tried to do an experiment by heating a certain amount of liquid water in a glass container and plotted a graph that showed the variation of temperature of water with time. (you may assume that he supplied heat at a constant rate). So obviously when you heat something up, its temperature should increase with time. However the student supplied heat continuously,with no change in temperature of water between t1 and t2. Explain this phenomenon. b. Guess the temperature T of water during the time interval between t1 and t2..Explanation / Answer
a. it is the boiling temperature , the phase change b. 100 degree celcius
