Question

What type of solid is dry ice?

Answer 1

1. Dry ice is the solid form of Carbon dioxide$\left({\mathrm{CO}}_2\right)$.
2. The dry ice sublimates to form gas at $-78°\mathrm{C}$ and 1 atmospheric pressure.
3. Dry ice is a molecular crystal where the crystal lattice contains Carbon dioxide molecules rather than atoms of Carbon or Oxygen.
4. In molecular solid or molecular crystals, molecules are bonded together by a Van der Waals forces.
5. Molecular solids have a low melting point and are soft in nature due to poor intermolecular bonding.
