A great demonstration for the First Law of Thermodynamics is The air surrounding a combustion event absorbs the heat that is produced by the reaction.

How does thermodynamics work?

Physics' field of thermodynamics examines how heat, work, and temp relate to energy, entropy, the physical characteristics of matter, and radiation. The four principles of thermodynamics, which give a numerical description using measurable macroscopic physical quantities but may be interpreted in terms of microscopic constituents by statistical mechanics, regulate how well these quantities behave. Physical chemistry, biochemistry, chemical engineering, mechanical engineering, and other complicated subjects like meteorology are just a handful of the topics in science and engineering where thermodynamics is relevant.
