Binding energy per nucleon Vs number of nucleons curve is shown above which suggests that binding energy per nucleon increases initially (upto Fe) and then decreases.

When the number of nucleons in a nucleus increases the binding energy per nucleon-
Vapour is injected at a uniform rate in a closed vessel which was initially evacuated. The pressure in the vessel
(a) increases continuously
(b) decreases continuously
(c) first increases and then decreases
(d) first increases and then becomes constant.
When a hot liquid is mixed with a cold liquid, the temperature of the mixture
(a) first decreases then becomes constant
(b) first increases then becomes constant
(c) continuously increases
(d) is undefined for some time and then becomes nearly constant
For nuclei with A > 100,
(a) the binding energy of the nucleus decreases on an average as A increases
(b) the binding energy per nucleon decreases on an average as A increases
(c) if the nucleus breaks into two roughly equal parts, energy is released
(d) if two nuclei fuse to form a bigger nucleus, energy is released.
As the mass number A increases, the binding energy per nucleon in a nucleus
(c) remains the same
(d) varies in a way that depends on the actual value of A.
