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.
