Answer 1

Answer:

C. heat is gained by the ice cream

Answer 2

Answer:

b) B and C

Explanation:

b) B and C

An example of an open system, where energy can flow from the system to its surrounds or vice versa, is the melting of ice cream.

The physical process of ice cream melting involves the ice cream absorbing heat from its environment and melting as the temperature rises. As a result, the environment loses heat while the system, or ice cream, gets it. As a result, both B and C are accurate.

All those tiny air bubbles escape as the ice cream melts because its fragile molecular structure collapses. Due to the lack of air to fluff it up, ice cream that has been melted and then refrozen is harder and slightly smaller.
