1. What is the definition of heat of fusion?
The energy required to raise the temperature of a substance by 1°C.
The energy absorbed or released during a phase change from liquid to gas.
The amount of energy required to change a substance from solid to liquid at its melting point.
The amount of energy released when a substance changes from gas to liquid.
2. What happens to the temperature of a substance during a phase change, such as melting?
It increases rapidly.
It decreases rapidly.
It remains constant.
It fluctuates unpredictably.
3. The heat of fusion is a type of heat, meaning it is absorbed or released without a change in temperature.
4. When a substance freezes, it energy, and the process is called .
5. Explain, in terms of molecular energy, why energy is required to melt a solid even though its temperature does not change.
