If mercury cannot be melted then why does it have melting point?

Answer 1

The Metal

Almost (maybe all) metals have the typical three states: solid, liquid and gaseous. So, mercury like most other metals has a freezing point (- 39 C) where it becomes a solid.

The Planet

The planet Mercury has an 88-Earth-day orbit around the Sun, and a very slow rotational period of 56.8 Earth days. Combined, these produce an extended "solar day" of 176 Earth days in which any location on the surface spends about 88 days out of the sunlight. With no appreciable atmosphere to carry heat, the temperature on the side facing away from the Sun plummets to -170 degrees C as it radiates away its heat into the vacuum of space.

Conversely, the surface temperature in sunlight will rise to +430 degrees C.

Answer 2

Mercury does have a melting point, which is -38.83°C. However, due to its unique properties as a metal, it remains in a liquid state at room temperature and does not solidify easily. Instead of melting into a solid form, it undergoes a phase change from liquid to solid at its melting point.

Answer 3

Because mercury is already a liquid at room temperature. If you were to make mercury (the element) very, very cold, it would freeze. Then, it would be possible to melt it.

Answer 4

Because Mercury does not have any atmosphere, any heat gained from the Sun is radiated away as Mercury slowly revolves.

Answer 5

there is no north pole on mercury if so the sun would.

Answer 6

It does melt. But it takes a lot of time to melt down.

Answer 7

man cause it can have what it whats sounds smart right [NO]

Answer 8

It's far enough away from the sun that it doesn't get so hot as to melt. Its temperature range is -173C to 525C.

Answer 9

because it is hot
