Answer

Brief Explanations:

A basic coffee - cup calorimeter is an insulated container. When a substance is added to the water in it, heat is transferred between the substance and the water. By measuring the temperature change of the water (using a thermometer), along with knowing the mass and specific heat of water, we can calculate the heat gained or lost by the substance according to the formula $q = mc\Delta T$ (where $q$ is heat, $m$ is mass, $c$ is specific heat, and $\Delta T$ is temperature change).

Answer:

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.
