The capacitance of a parallel plate capacitor
decreases when the temperature between the plates decreases
increases when the potential difference between the plates is increased
is greater without a dielectric between the plates than with dielectric
is greater with dielectric between the plates than without dielectric.
Explication
When a dielectric is placed between the plates, it increases the capacitance by reducing the electric field and allowing more charge to be stored.
