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.
What happens during the slow melting point determination?
During slow melting point determination, a solid sample is gradually heated and observed for the temperature range over which it transitions from solid to liquid. This process allows for a more precise measurement of the melting point, as it provides time for the sample to reach thermal equilibrium. The melting point is recorded when the first drop of liquid is observed until the entire sample is melted. This method is useful for assessing the purity of a substance, as pure compounds have sharp melting points, while impure samples tend to have broader melting ranges.
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.
Will paraffin wax dissolved in hexane remain liquid at room temperature?
Yes, paraffin wax dissolved in hexane will remain in a liquid state at room temperature. Paraffin wax typically has a melting point around 46-68°C (115-154°F), but when dissolved in hexane, the solution can remain liquid at lower temperatures due to the properties of the solvent. However, the specific concentration and conditions can affect the exact behavior of the mixture.
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)
