Quantities of heat Q can be measured using a container called

The correct answer is "Calorimeter". A calorimeter is a container used to measure the amount of heat involved in a chemical reaction or physical process. It's used to determine the amount of heat energy absorbed or released during a reaction. The calorimeter is designed to prevent heat loss to the surrounding environment, allowing for an accurate measurement of the heat being produced or absorbed. The measurement of heat energy is usually done in units of joules (J) or calories (cal). Calorimeters can come in various forms, including bomb calorimeters for high-pressure reactions and coffee cup calorimeters for low-pressure reactions.
