Question

Which statements of the following is true

(a) Isobaric process is one of contestant pressure

(b) Isothermal process is one of contstant temperature

(c) Closed syste, is one in which mass does not crosss its boundry

Answer 1

All the above three statments are true i.e (a),(b) and (c) are true.

(a) Isobaric process is one of the constant pressure.

When the pressure in the system is constant and does not change with any parameter so the process is Isobaric process.

for isobaric process

(b) Isothermal process is one of the constant temperature.

In isothermal process the temperature of the system does not vary with any other parameter. for isothermal process

(c) Closed system is one in which mass does not cross its boundry

In closed system the there is no change of mass while the open system is one in which mass can also change with other parameters.

Example of closed system is foot ball. The gas in the ball is remains constant while the temperature and hemce energy got interacted.
