The melting point of lead is 327.46℃. So when the temperature is 328℃, the lead will change from a solid to a liquid. When the temperature is 874 or 601℃, the lead is already liquid. So the answer is (3).

Answer: The correct answer is option 3.

Explanation: The phase change from solid to liquid occurs when the substance is at a constant temperature. That temperature is known as the melting point of that substance.

[tex]Solid\rightleftharpoons Liquid[/tex]

We are asked the temperature at which Lead changes from solid to liquid. As, the melting point of lead is 328°C, so this is the temperature at which Lead changes from solid to liquid.

Hence, the correct option is 3.
