Define reversible and irreversible processes.

Define reversible and irreversible process. Explain with an example of each process.

Write one difference between reversible and irreversible processes.

Write three differences betweenn reversible and irreversible processes. Melting of ice at 0^(@)C and 1 atm pressure is a reversible process-explain.

Write twodifferences between reversible and irreversible process.What is open system?

Write two differences between reversible and irreversible process? Why enthalpy gets move tnportance than internal energy in the discussion of thermodynamics.

When a liquid is stirred vigorously. It becomes hot. Is it a reversible or an irreversible process? Explain.

Why is the change in any state function in a cyclic process zero? Is the change in any state function for both reversible and irreversible cyclic process zero?

Differentiate irreversible and reversible reactions.

Are the following changes reversible or irreversible? Give proper explanations: (i) Melting of ice at 0^(@)C and 1 atm pressure (ii) The pressure of a gas enclosed in a cylinder fitted with a piston is 5 atm. The gas is expanded against an external pressure of 1 atm.
