Question

Example of closed system in thermodynamics

Answer 1

definition of closed system:
mass flow=0
and
energy flow !=0

So there's many examples of these type of system like water bottle, box etc.

Answer 2

Answer:

(1) When an inflated balloon is punctured, the air

inside it suddenly expands and escapes into the

atmosphere. During the rapid expansion, there is

no uniformity of pressure, temperature and density.

(2) When water is heated, there is no uniformity of

pressure, temperature and density. If the vessel is

open, some water molecules escape to the atmos-

phere.
