Detailed explanation-1: -Water droplets form on the outer surface of the container containing a cold substance due to Condensation. The temperature of the container is cold enough to cool down the water vapour in the surrounding air, so it turns from gaseous to liquid state.
Detailed explanation-2: -When water molecules in the air get cold, they slow down, join together, and become tiny drops of liquid water. This process is called condensation. This is what happens when water molecules in the air touch the outside of the cold cup that is exposed to air.
Detailed explanation-3: -For example, condensation occurs when water vapour (gaseous form) in the air changes into liquid water when it comes in contact with a cooler surface. When the water in the air comes in contact with a cold surface, it condenses to form water droplets.
