Consider the following statements regarding the effect of temperature on the dielectric constant of an insulator.
1. The dielectric constant increases due to thermal energy facilitating the alignment of the dipole with the applied field.
2. The dielectric constant decrease due to the randomizing effect of thermal energy.
3. The dielectric constant decreases due to an increase in the volume of the material.
4. The dielectric constant increases due to the creation of new dipoles.
