Conditions and Characteristics of isothermal changes

The change in which pressure and volume of a gas are changed but the temperature remains constant that change is called isothermal change and the process by which this change occurs is called isothermal process.

Conditions for isothermal changes

  1. The gas is to be kept in a good conducting vessel or container.
  2. Heat capacity of the media surrounding the container must be very high,
  3. Change of pressure is to be made slowly and slowly.
  4. Temperature is to be maintained constant either by supplying or by removing

Characteristics of isothermal change

  1. Change of pressure and volume of a gas by keeping the temperature constant is called isothermal change.
  2. In this change, necessary heat is either supplied or removed.
  3. It is a very slow process.
  4. In this change, the container should have good thermal conductivity.
  5. All surroundings of the container should have a very high thermal capacity.
  6. Isothermal change obeys Boyle’s law i.e., PV = constant.
  7. The isothermal curve is comparatively less steep.
