Question

Which statement describes how a basic coffee cup calorimeter works? A) It measures the mass of a substance given the specific heat and temperature of water in a cup of known size. B) It measures the density of a substance given the mass, specific heat, and temperature of water in a cup of known size. C) It uses the mass and specific heat of water along with a pressure gauge to measure the gain or loss of energy when a substance is added. D) It uses the mass and specific heat of water along with a thermometer to measure the gain or loss of energy when a substance is added.

Answer 1

A calorimeter experiment is a set-up that provides insulation so that no heat escapes to the surroundings and all energy can be accounted for. It can be done at either constant volume or constant pressure. So, the answer to this is knowing the mass of water, the specific heat which is an empirical data, and the change in temperature which can be measured using a thermometer. This experiment could measure the mass of an unknown substance added or the specific heat of the substance or the calorimeter. The answer is D.

Answer 2

Answer:

D: It uses the mass and specific heat of water along with a thermometer to measure the gain or loss of energy when a substance is added.
