How do you do Calorimetry? We've had it in class for about a week and I still don't understand it so does anyone have any simple step by steps for it?

It basically works like this:

You dry out the food

put it in this ceramic oven thingy surrounded with water

burn the food

the water will heat up

measure the water temperature in f

= calories

Calorimetry is the science or act of measuring changes in state variables of a body for the purpose of deriving the heat transfer associated with changes of its state due, for example, to chemical reactions, physical changes, or phase transitions under specified constraints.

in this case, you're finding the amount of energy is contained within it when combusted

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
