Why paraffin used for determination of melting point?
i dont know asked some one else to asked
Does matter change from solid to liquid at freezing point or at melting point?
Matter changes from solid to liquid at its melting point, because this change is called melting. Freezing point is about the same as melting point, but it can be slightly lower, so melting point should always be used.
is the melting point the temperature at which you given liquid changes to gas?
The melting point is the temperature at which a solid becomes a liquid.
Results from a change at the melting point?
At the melting point a solid become a liquid.
Are the melting point of solid and freezing point of liquid of a substance different?
yes the melting point of solid and freezing point of liquid of a substance is differ but in the case of water the melting and freezing point is same.
Why we use paraffin for determination of melting point?
Liquid paraffin is used in thermostatic baths, to maintain a constant temperature.

In the experiment of determining melting point why each time fresh paraffin liquid should be taken?
Paraffin oil is nontoxic, noncorrosive and stable.
What is the Paraffin Wax freezing Point?
The freezing point is the same as the melting point; it is the point at which the paraffin transitions from solid to liquid. 37 °C (99 °F)
What is the boiling point of liquid paraffin?
Paraffin is a class of hydrocarbons called Alkane the most basic alkane being methane. Methane has a boiling point of -161 degree Celsius. As it goes higher the bp increases as the energy required to break the hydrogen bonding increases.
Conclusion of determination of melting point?
Melting point of a solid involves the temperature changing from solid to liquid. Solid and liquid exist in in-equilibrium. The liquid to solid process is known as freezing or crystallisation.The principle of observing the disappearance rather than the forming of ice is known as the melting point.Source(s):Wikipedia
What is the melting point of liquid nitrogen?
Liquid nitrogen has no melting point. A melting point is the temperature when a solid turns into a liquid. Since liquid nitrogen is already a liquid, it has no melting point. It is already melted, compared to solid nitrogen.
What is a temperature at which solids start to change from a liquid?
the melting point
Is a condensation point the same as a melting point?
No, Gas--->liquid (condensation). Solid---->liquid (melting)
Which term is defined as the temperature at which a substance changes from a solid to a liquid state?
melting point
If a substace is a liquid already what would it be before the melting point?
It would be solid before it reached the melting point. If it is liquid, it has already reached the melting point.
What do you call the temperature at which a solid changes to a liquid?
This is the melting point.
