Define Isothermal and Isobaric process. |
|
Answer» Isobaric Process Anisobaric processis one where the pressure of the system (often a gas) stays constant. 'Iso' means the same, and 'baric' means pressure. Pressure is related to the amount of force that the molecules apply to the walls of the container. Imagine that you have a gas inside a movable piston and you heat that gas up. By heating the gas up you make the molecules move faster, which would normally increase the pressure. But at the same time the piston expands, increasing the volume and giving the molecules more room to move. Since the walls of the container are now bigger, the pressure can stay the same even though the molecules are moving faster. That makes it an isobaric process. Isothermal Process Anisothermal processis one where the temperature of the system stays constant.Thermalrelates to heat, which is in turn related to temperature. Temperature is the average heat (movement) energy of the molecules in a substance. |
