But students learn that the calorie is a unit of HEAT ENERGY.
Isn't is possible to raise the temperature of 1 g ...... by shaking

Why use the term CALORIE at all if it is just as easy to raise
the temperature of 1g ..... with 4 joules of energy ....any kind
of energy?
I'm willing to avoid calories when and if it makes sense to, but Ithing.
don't follow this argument. It's not "just as easy;" it's the same
If we shake 90 grams of water and find that it's temperature rises by .5K
it's certainly easier to calculate the work done on it in calories
than in joules.
