Answer 1

Dry ice is a crystalline solid in which the particles are held together by​ weak van der Waals forces.

- The crystalline solid Carbon dioxide (CO2) is commonly named as dry ice.

- It is a non-polar molecule that has no dipole moment.

- Hence, the attractive intermolecular forces which hold its particles together are weak van der Waals forces (or we can say dispersion forces).

Answer 2

Weak van der Waals forces.

Explanation:

• Weak van der Waals forces is a process or force under which weak electrical force usually acts by solidifying the molecules present in the gases first into liquid and then their organic compounds into solids.
• Dry ice is an example of this.
