Questions:

1) Using the data from wattmeter, calculate the actual power consumed by the kettle during the experiment.

2) How does the power consumed by the kettle (in 1) compare to the advertised power consumption?

3) Using the temperature data, calculate the amount of power that went in to heating the water from room temperature to the boiling temperature.

4) Using above data, calculate the efficiency of the kettle that was used in your experiment during the boiling process.

5) Explain your answer from 4 in the context of the first law of thermodynamics?

6) With the aid of sketch, explain the working of the temperature measuring device that was used in the experiment.

7) Draw a graph of time (on x-axis) versus temperature (on y-axis). Why does the temperature of water remain constant once it reaches its boiling temperature?

8) From the power consumed during the evaporation process, calculate the amount of water that should have evaporated. How does this compare to the actual amount evaporated? Explain any difference between the two.

9) Show the above process on a PV diagram. Show the saturation curve, and label, i.e. the value of pressure and specific volume at the beginning and end of evaporation, assuming that all the water is evaporated during this process.

10) What is the maximum efficiency possible for a heat engine that operates between the maximum and minimum temperature that you recorded in your experiment?
