Why paraffin used for determination of melting point?
i dont know asked some one else to asked
What happens to the melting point of paraffin wax if the pressure increases?
If the pressure increases, the melting point of paraffin wax also increases. This is because an increase in pressure makes it harder for the molecules to break free from their ordered arrangement and transition into the liquid phase, thus requiring a higher temperature to melt.
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.
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.
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.
In the experiment of determining melting point why each time fresh paraffin liquid should be taken?
Each time fresh paraffin liquid should be taken in the experiment of determining melting point to ensure accurate and consistent results. Reusing the same sample may introduce impurities or contaminants, leading to inaccurate melting point measurements. Using fresh paraffin liquid each time helps to eliminate any potential variables that could affect the melting point determination.
Why we use paraffin for determination of melting point?
Paraffin is a commonly used material for determining the melting point of organic compounds because it has a well-defined melting point of 54-57°C and does not react with most organic compounds. This makes it a suitable medium for accurately measuring the melting points of various substances without interference.

Why do you use liquid paraffin to detect melting point and boiling point in a lab?
Because the phase changes (solid and liquid, and even vaporization) are within safe temperature limits and the heat of fusion (enthalpy) is low compared to water -- i.e. it becomes solid again faster than freezing water. Unless you have some dry ice handy.
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 happens when paraffin wax melts?
When paraffin wax melts, its solid crystals break down, turning into a liquid form. The melting point of paraffin wax is typically between 99°F and 131°F (37°C and 55°C), depending on the specific type of paraffin wax.
What do you call the temperature at which a solid changes to a liquid?
This is the melting point.
What happens to the melting point of paraffin wax if the pressure increases?
If the pressure increases, the melting point of paraffin wax also increases. This is because an increase in pressure makes it harder for the molecules to break free from their ordered arrangement and transition into the liquid phase, thus requiring a higher temperature to melt.
What is the boiling point of liquid paraffin?
Oh, dude, the boiling point of liquid paraffin is around 370 degrees Celsius, but like, who really needs to know that, right? I mean, unless you're planning on hosting a paraffin boiling competition or something. Just don't try to cook your dinner with it, that's all I'm saying.
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.
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?
The term defined as the temperature at which a substance changes from a solid to a liquid state is called the melting point.
