Answer the following true or false A process that violates t

Answer the following true or false. A process that violates the second law of thermodynamics violates the first law of thermodynamics. When a net amount of work is done on a closes system undergoing an internally reversible process, a net heat transfer of energy from the system also occurs A closed system can experience an increase in entropy only when a net amount of entropy is transferred into the system. The change in entropy of a closed system is the same of every process between two specified end states.

Solution

1. False

Reason:- Consider a ball of iron at 55 Celsius added to a bath of water of twice the mass initially at 25 C. The water cools off to 22 C, and the iron ball heats up to 79 C.it is still perfectly OK with the first law of thermodynamics.

2. False

Reason:- Consider adiabatic and quasistatic compression of gases. in this process work is converted to internal energy rather than heat energy

3.False

Reason:- consider a air tank is connected to vaccum tank and both tanks are isolated from atmosphere in this process entropy is increasing.

4.True

Reason:- Entropy is a state function
