Expert Answer:

When battery across the plates of charged capacitor is disconnected and dielectric slab is introduced between the plates:
 
i) Charge remains constant.
ii) Electric field strength decreases.
iii) Capacitance increases.
iv) Potantial decreases.
v) Energy stored decreases.
vi) energy density decreases.
