Question

Which of the following curves describes what happens to the temperature of a water-ice mixture originally at 0 degree C when heat energy is transferred to it at a constant rate, at standard (1atm) pressure (at sea level). Suppose you transfer a certain amount of heat energy to a known amount of a liquid in a perfectly insulated cup and the temperature changes. Then, you decide to alter the experiment in several different ways. Match the alterations listed below with the best description of the total change in temperature compared to that measured in the original experiment (before the alteration): Transfer more heat energy Heat for a longer time but transfer the same total heat energy. Start with more liquid in the cup. Increase the starting temperature of the liquid. Use an equal mass of liquid that has a larger specific heat. Use the same volume of a denser liquid that has the same specific heat. The temperature change will be the same. The total change in temperature will be larger. The total change in temperature will be smaller.

Explanation / Answer

Solution question 7: the temperature of water ice mixture is 0 C as ice is present there. So, until all the ice melt, temperature will remain fixed at 0 C. Then the temperature of the system will rise gradually and again comes to a halt at evaporation point. So, Green dotted line in the left panel is the right answer.

Solution question 1: (a) For alteration 1, option B.

(b) For alteration 2, option A.

(c) For alteration 3, option C.

(d) For alteration 4, option A.

(e) For alteration 5, option C.

(f) For alteration 6, option C.
