what is the isothermal
Answers
Explanation:
The science of physics studies objects and systems to measure their motions, temperatures, and other physical characteristics. It can be applied to anything from single-celled organisms to mechanical systems to planets, stars, and galaxies and the processes that govern them. Within physics, thermodynamics is a branch that concentrates on changes of energy (heat) in the properties of a system during any physical or chemical reaction.
The "isothermal process", which is thermodynamic process in which the temperature of a system remains constant. The transfer of heat into or out of the system happens so slowly that thermal equilibrium is maintained. "Thermal" is a term that describes the heat of a system. "Iso" means "equal", so "isothermal" means "equal heat", which is what defines thermal equilibrium.
The Isothermal Process
In general, during an isothermal process there is a change in internal energy, heat energy, and work, even though the temperature remains the same. Something in the system works to maintain that equal temperature. One simple ideal example is the Carnot Cycle, which basically describes how a heat engine works by supplying heat to a gas. As a result, the gas expands in a cylinder, and that pushes a piston to do some work. The heat or gas has to then be pushed out of the cylinder (or dumped) so that the next heat/expansion cycle can take place. This is what happens inside a car engine, for example. If this cycle is completely efficient, the process is isothermal because the temperature is kept constant while pressure changes
