The answer is d I’m sure

Answer 2

Option(A)

The container contains 12 grams of water and no ice

Step-by-step explanation:

When the student kept the ice in the container, the ice starts to melt as the air temperature around the ice is warmer than the temperature of the ice itself.

The solid particles in the ice absorbs the heat from the air, allowing the particles in the ice to move freely. Hence, melting takes place and the student finds water and no ice in the container.
