Liquid paraffin is used in the determination of melting point because it has a known and consistent melting point of around 40-60°C. This allows for a reliable reference point to calibrate and set the temperature of the melting point apparatus before testing other substances. Liquid paraffin also has a low volatility, ensuring that it remains stable throughout the duration of the experiment.

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 the melting point. At the melting point, the solid phase transitions into the liquid phase as heat energy is absorbed, causing the particles to gain enough kinetic energy to overcome intermolecular forces and change their arrangement from a solid structure to a liquid structure.
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?
Liquid paraffin is used because it has a relatively high and consistent boiling point and melting point, making it a suitable medium for observing the changes in state of other substances without interfering with their properties. This allows for accurate determination of the melting and boiling points of the substance being tested.
What is the Paraffin Wax freezing Point?
The freezing point of Paraffin Wax is typically around 47-64°C (116-147°F), depending on the specific grade and composition of the wax.
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.
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 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 do you call the temperature at which a solid changes to a liquid?
This is the melting point.
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, a condensation point is the temperature at which a substance changes from a gas to a liquid, while a melting point is the temperature at which a solid changes to a liquid.
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.
