Questions asked by users might not always be phrased in the clearest way.
Chandeliers are not directly related to chemistry. However, here's a brief explanation of the other terms you mentioned:
Exothermic Reaction: A chemical reaction that releases energy into the surroundings, usually in the form of heat. Examples include combustion (burning) and the reaction of sodium with water.
Cyclic Process: A process that repeats itself in a continuous cycle. In chemistry, this is often seen in thermodynamic cycles, such as the Carnot cycle, which describes the ideal efficiency of a heat engine.
Isochoric: A process that occurs at constant volume. In a chemical reaction, this means the volume of the system remains the same, even though other parameters like pressure or temperature might change.
