A process in which work is done without producing an equivalent increase in the KE or PE is

A process in which work is done without producing an equivalent increase in the kinetic or potential energy of any system is

Options:

a. a reversible process
b. an irreversible process
c. a quasi-static process
d. none of the above

Correct Answer: b. an irreversible process

Explanation

When a work is done without producing an equivalent increase in the kinetic or potential energy of any system then there are some energy losses in the process. This is called as dissipative effect. Work is dissipated in this process.

In a dissipative effect the energy is transformed from one form to another form and the final form of energy has a less capacity to do mechanical work. Thus this process becomes irreversible as we can not reverse this process without any external effect on the system.
