Question

digby wants to determine how many calories are in his bag of chips. which calorimeter should he use?
coffee cup calorimeter
bomb calorimeter
he could use both types of calorimeters.
he cannot use either.

Explanation:

To determine the calories in chips (a food sample), a bomb calorimeter is used for measuring the heat of combustion of substances, including food (since food combustion releases energy measured as calories). A coffee cup calorimeter is for solution - based reactions at constant pressure, not suitable for burning solid food like chips. So the correct choice is the bomb calorimeter.

Answer:

B. bomb calorimeter
