NOTE: I see you already provided simple answers. I will develop them further.
Answer and Explanation:
The Latin word calor means "heat," and meter comes from the Greek word meaning "to measure." What do you think a calorimeter does?
Taking the explanation above as a start point, I believe a calorimeter is an instrument used to measure heat or heat energy and any changes in it.
Where have you heard the word calorie before? What do you think a calorie is?
I have commonly heard the word calorie in relation to food and exercise. People often mention how many calories or how much energy a certain food or meal will provide them. People also worry about how many calories or how much energy they will spend by doing a certain work out. I believe a calorie refers to the heat energy or simply the energy we absorb from food and burn throughout the day, and even in our sleep. Also, in chemistry, a calorie is a unit of energy or heat energy, be it in connection to food or not.
