Suppose you have a system made up of water only, with the container and everything beyond being the surroundings. Consider a pro
cess in which the water is first evaporated and then condensed back into its original container.
Is this two-step process necessarily reversible?
2 answers:
Answer:
Yes
Explanation:
The possibility of evaporating and condensing is a proof of reversible reaction
Answer:
No
Explanation:
No, because there is no evidence that the surroundings are also restored to their original state.
cannot be undone by exactly reversing the change to the system; Spontaneous processes are irreversible.

Answer:
Explanation:
The expression for the calculation of the enthalpy change of a process is shown below as:-
Where,
is the enthalpy change
m is the mass
C is the specific heat capacity
is the temperature change
Thus, given that:-
Mass of object = 36.2 g
Specific heat = 12.5 J/g°C
So,
