Respuesta :

The dry ice is at a lower temperature and allows ice cream to stay frozen for longer time while in transit. Also, the salt ice will melt and may spoil the ice cream. Dry ice will not melt but will sublimate and thus will not affect the ice cream.

Vendors keep 'dry ice' in their ice cream boxes​ in order to prevent melting of dry ice.

Why vendors keep 'dry ice' in their ice cream boxes​?

Dry ice melts if it is placed in the open space because the carbondioxide gas is compressed with pressure. As carbon dioxide changes to gas, it escape to the atmosphere. If you use an airtight container such as ice cream box, the gas cannot escape.
