Question

-why is oil used instead of water to determine the melting point?‌
2-what kind of oil is used at the melting point?what is the reason you are using that oil?
3-why is the temperature different from the meltung point?​

Answer 1

Answer:

1 Answer. 2Paraffin oil is used for determination of boiling point and melting point for the following reasons: It has a very high boiling point and so it can be used to maintain high temperatures in the boiling and melting point apparatus without loss of the substance.

Explanation:

3 Melting point, temperature at which the solid and liquid forms of a pure substance can exist in equilibrium. As heat is applied to a solid, its temperature will increase until the melting point is reached. More heat then will convert the solid into a liquid with no temperature change.
