Answer 1

The amount of energy transferred during a phase change depends on the specific phase change being referred to and cannot be determined without further information.

Step-by-step explanation:

The amount of energy transferred during a phase change is called the heat of vaporization or heat of fusion. Based on the information provided in the table, the heat of fusion for water is 334 J/g and the heat of vaporization is 2,260 J/g.

Since the question specifically asks about the phase change shown on the cooling curve, we need to determine if the phase change is from solid to liquid or from liquid to gas. Without additional information, we cannot determine which phase change is represented on the cooling curve.

Therefore, we cannot calculate the exact amount of energy transferred during the phase change without knowing the specific phase change being referred to.
