Question

Aarya perform melting point experiment in the Chemistry laboratory a) tell whether the melting point of two different substance is same or different b) the substance will have low melting point hydrogen or sodium​

Answer 1

Answer:

the melting point of two substances are different

and the melting point of sodium is high which is 801° where as for hydrogen its -259°

Answer 2

Inference for melting point experiment in Chemistry by Araya.

a) Melting point of two different substances

• The temperature at which the solid state of the substance converts into liquid state, it is called as melting point of the substance.
• The melting of two different substance is always different. For example among metals and non-metals, the former has a low melting point whereas the latter has a high melting point.

b) Melting point of hydrogen and sodium

• The melting point of hydrogen and sodium are -259.14°C and 97.79 °C respectively.
• As the value of hydrogen is negative, it has less melting point than sodium.
• Thus it is inferred that the melting point of hydrogen is less when compared to sodium.
