A molecule of a substance has a permanent electric dipole moment of magnitude `10^(-30)` cm. A mole of this substance is polarised by applying a strong electrostatic field of magnitude `10^(7) V m^(-1).` The direction of field is charged by an angle `60^(@).` The heat released by the substance in aligning its dipole along the new direction of the field is
