No.StatementT/F1.For every cyclic process, the final state of the surroundings is the same as the initial state of the surroundings. 2.For a closed system at rest with no fields present, the sum q+w has the same value for every process that goes from a given state 1 to a given state 2. 3.∆H is defined only for a constant-pressure process. 4.For a constant-volume process in a closed system, ΔH=ΔU 5.If a closed system at rest in the absence of external fields undergoes an adiabatic process that has w = 0, then the system's temperature must remain constant. 6.A change of state from state 1 to state 2 produces a greater increase in entropy of the system when carried out irreversibly than when done reversibly. 7.The system's entropy change for an adiabatic process in a closed system must be zero. Find the number of false statements

Accepted Answer

In every statement,Only 2nd statement is true.1 Final system state is same.2 U is a state function.3 ∆H is defined for all processes.4 For a chemical reaction, ΔH=ΔU+VΔP5 For ideal gases only it is valid.6 S is a state function.7 Only for reversible adiabatic process it is zero.

S. No.	Statement	T/F
1.	For every cyclic process, the final state of the surroundings is the same as the initial state of the surroundings.
2.	For a closed system at rest with no fields present, the sum q+w has the same value for every process that goes from a given state 1 to a given state 2.
3.	$∆ H$ is defined only for a constant-pressure process.
4.	For a constant-volume process in a closed system, $Δ H = Δ U$
5.	If a closed system at rest in the absence of external fields undergoes an adiabatic process that has w = 0, then the system's temperature must remain constant.
6.	A change of state from state 1 to state 2 produces a greater increase in entropy of the system when carried out irreversibly than when done reversibly.
7.	The system's entropy change for an adiabatic process in a closed system must be zero.
