Question

The hot working temperature of lead

• A. $300^\circ\text{C}$
• B. $100^\circ\text{C}$
• C. $200^\circ\text{C}$
• D. Room temperature

Hint:

Hot working does not necessarily mean "hot to touch."
It simply means working a metal above its recrystallization temperature.
Lead at room temperature is being hot worked, while iron at $400^\circ\text{C}$ is still being cold worked.
