Question

Which of the following metal have the highest melting and boiling point?

• A. Iron
• B. Gold
• C. Tungsten
• D. Copper

Answer 1

The correct option is C

Tungsten

Melting point:- The temperature at which a solid convert to liquid is called melting point and this phase transition from solid to liquid is called melting.

Boiling point:- The temperature at which a liquid convert to gas is called boiling point and this phase transition from liquid to solid is called boiling.

Out of the given metals, tungsten has the highest melting point $3414{}^{\circ }C$ and boiling point $5555{}^{\circ }C$. Because it has a high melting point it is used to make the bulb filaments.
