Question

the melting point of Mn4N is
1). same as that of manganese metal.
2). higher than that of manganese metal.
3).one third to that of Manganese metal.
4). one fourth to that of manganese metal.

Answer 1

Answer:

higher than that of manganese metal....

Answer 2

Answer:

Higher then Manganese metal

Explanation:

Melting point of Mn = 1246°C

And

Melting point of Mn4N  = 4892°C

.. The softness of substance depends upon weight and is usually calculated  at standard weight.

The temperature point  at which fluid change into solid is called  solidification or crystallization point.  

An increasingly explicit meaning of the point of solidification is the temperature at which the strong and fluid periods of a substance are in harmony at a predefined weight.
