As the atmospheric pressure inside the building slowly decreases, the ballon expands and slowly does work on the air outside the balloon. At the same time energy is slowly transferred into the balloon as heat. The net result of these two processes is that the air inside the balloon stays at the same tempearture as the air outside the balloon. Thus, the internal energy of the balloon's air doe snot change. The energy transferred out of the balloon as work is matched by the energy transferred into the balloon as heat. That example is a close approximation of an isothermal process. In an isothermal process, the system's temperature remains constant and internal energy does not change when energy is transferred to or from the system as heat or work.
In an isothermal process, the system's temperature remains constant and internal energy does not change when energy is transferred to or from the system as heat or work. In an isothermal process in a particially inflated balloon, small amounts of energy are removed as work. Energy is added to the gas within the balloon's interior as heat so that thermal equilibrium is quickly restored.
In an isothermal process, the system's temperature remains constant and internal energy does not change when energy is transferred to or from the system as heat or work.Energy is added to the gas within the balloon's interior as heat so that thermal equilibrium is quickly restored.
The system's temperature remains constant and internal energy does not change when energy is transferred to or from the system as heat or work. It is prety cool. It is sweet.
It is when heat or work are transfered and the internal energy are not affected. The temperature also remains constant. In the process small amounts of work are released as heat.
An isothermal process occurs when the system's temperature remains constant and internal energy does not change when energy is transferred to or from the system. An example is a tire slowly inflating. They are not normally violent or sudden processes.
