Assignment:

Expert Will efficiency of the appliances above improve with more water to heat? Find an appliance in your home that can be used to heat water. Determine the efficiency of this appliance by repeating part 1 above. This time you will vary the amount of water only (you must maintain the same input energy) and determine whether or not the mass of water heated has any effect on the appliance's efficiency.

1. For this experiment you will only examine one appliance. How can you ensure that the INPUT energy is identical for all trials? (hint: look at how it was calculated in Part 1)

2. You must make sure that your water never boils for this experiment to have validity.

a. Why must the water never boil? How does this make it difficult to measure the output heat energy given to the water?

b. Since we want the operation times to be equal for all (see question 1 above), and we can't have the water boil, should we start with the smallest or largest amount of water to set our times? Explain why.
