Question

Is freezing chocolate-covered bananas a physical or chemical change?

a) Physical
b) Chemical

Answer 1

Freezing chocolate-covered bananas is a physical change because it involves a change in state without altering the chemical structure of the bananas or chocolate.

Step-by-step explanation:

Freezing chocolate-covered bananas is a physical change, not a chemical change. During the freezing process, the bananas and the chocolate undergo a change in state from liquid or soft to solid, but their chemical structures are not altered.

This is similar to the example of ice melting, where water changes from solid to liquid form (H₂O(s) → H₂O(l)), which is also identified as a physical change. Thus, the key characteristics such as taste and nutritional content of the bananas and chocolate remain the same after freezing.

The freezing of chocolate-covered bananas is a physical change. This is because the change does not alter the chemical composition of the chocolate or the banana. The state of matter changes from a liquid to a solid when you freeze chocolate-covered bananas, but the individual molecules of the chocolate and banana remain the same.
