Thermal sciences is a branch of science that focuses on the study of heat, energy, and temperature. It encompasses various fields, including thermodynamics, heat transfer, and fluid mechanics. These areas help us understand how energy moves and changes form, which is essential in applications like engines, refrigeration, and climate control. In thermal sciences, researchers analyze how heat interacts with different materials and systems. This knowledge is crucial for designing efficient machines, improving energy use, and developing new technologies. By studying the principles of thermal sciences, we can better manage energy resources and address challenges related to climate change and sustainability.
