Question

The physical constant, ___________ is less for $D_2$O as compared to that of $H_2$O.

• A. Density (${gml}^{-}$${}^1$) at ${200}^{\circ }$C
• B. Boiling point
• C. Dielectric constant at ${200}^{\circ }$C
• D. Latent heat of vapourisation (${Jg}^{-}$${}^1$)

Answer 1

The correct option is C
