Suppose a 10.00-kg mass drops through a height difference of 3.00 m, and the resulting work is used to turn a paddle in 200.0 g water, initially at 15.00C. The final water temperature is found to be 15.35C. Assuming that the work done is used entirely to increase the water temperature, calculate the conversion factor between joules and calories.

  • a)
    1 calorie ≈5.2J

  • b)
    1 calorie ≈4.2J

  • c)
    1 calorie ≈6.1J

  • d)
    1 calorie ≈3.2J

Correct answer is option 'B'. Can you explain this answer?

To solve this problem, we need to find the amount of work done by the mass as it falls through the height difference, and then convert this work into calories.

The work done by the mass is given by the formula: W = mgh, where m is the mass (10.00 kg), g is the acceleration due to gravity (9.8 m/s^2), and h is the height difference (3.00 m).
W = (10.00 kg)(9.8 m/s^2)(3.00 m) = 294 J

To convert this work into calories, we need to use the conversion factor between joules and calories.
1 calorie = 4.184 J

So, the conversion factor between joules and calories is 1 calorie/4.184 J.

Therefore, the answer is a) 1 calorie.
