which statement describes how a basic coffee cup calorimeter works? it measures the mass of a substance given the specific heat and temperature of water in a cup of known size. it measures the density of a substance given the mass, specific heat, and temperature of water in a cup of known size. 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. 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

Brief Explanations:

A basic coffee - cup calorimeter is a constant - pressure calorimeter. It works by using the mass and specific heat of water (which are known) along with a thermometer to measure the temperature change of the water. The heat gained or lost by the water is related to the heat lost or gained by the substance added, based on the principle of conservation of energy. A pressure gauge is not used in a basic coffee - cup calorimeter, and it doesn't measure mass or density of a substance in the ways described in the other options.

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.
