Constant-Volume Calorimetry definitions Flashcards

The energy released when a mole of a substance undergoes combustion, typically involving carbon and hydrogen or oxygen.

The enthalpy change when one mole of a substance is burned completely in oxygen under standard conditions.

A device used for measuring the heat released during combustion reactions at constant volume.

A method where the volume remains fixed during a reaction, ensuring no expansion occurs in the calorimeter.

A reaction that releases heat, resulting in a negative enthalpy change.

The amount of heat required to raise the temperature of the calorimeter by one degree Celsius.

The difference in temperature measured before and after a reaction in the calorimeter.

The substance placed in the calorimeter that undergoes combustion to release heat.

Wires in the bomb calorimeter that ignite the combustion reaction.

An instrument used to measure the temperature change during the calorimetry process.

A device used to evenly distribute heat throughout the water in the calorimeter.

The enthalpy change when one mole of a substance is burned in excess oxygen at standard conditions.

The amount of heat released by the reaction, calculated as negative in exothermic processes.

The amount of heat absorbed by the calorimeter and water, equal to the heat lost by the reaction.

A formula representing the heat gained by a substance, where M is mass, C is specific heat, and T is temperature change.
