Note that 1 calorie (4.2 J) is the energy needed to raise 1 gram of water 1 degree, and recall that a food calorie is actually a kilocalorie
Use whatever approximations you need, but state what they are.

1) How much ice water must you drink and so heat up to equal the energy in a chocolate glazed donut?

2) Will drinking ice water work as a weight loss strategy?

3) How about standing on a windy mountaintop soaking wet?

4) How far must you job to burn off the calories in that donut?
