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.
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 is latent heat of fusion for paraffin wax?
The latent heat of fusion for paraffin wax is approximately 200 J/g. This means that 200 joules of heat energy is required to change 1 gram of solid paraffin wax into liquid paraffin wax at its melting point temperature.
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)
How long from the from the start of the experiment was the substance heated before all of the substance turned into a liquid?
It is impossible to tell how long from the start of the experiment it was before all of the substance turned into a liquid without more information about the experiment. Perform the experiment again and use a timer to determine the length of time required to turn the substance into a liquid through heating.
Why liquid paraffin used for determination of melting point?
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.

Discussion of an experiment of melting point?
The melting point experiment involves determining the temperature at which a solid substance transitions to a liquid state. This is typically done by heating the substance slowly and observing the temperature at which the first droplet of liquid is formed. Melting point is a unique physical property of a substance and can help identify unknown compounds or assess the purity of a sample. Factors such as proper calibration of equipment and avoiding contamination are important for accurate results in this experiment.
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.
Which liquid has a higher density between water and paraffin?
Water
What is latent heat of fusion for paraffin wax?
The latent heat of fusion for paraffin wax is approximately 200 J/g. This means that 200 joules of heat energy is required to change 1 gram of solid paraffin wax into liquid paraffin wax at its melting point temperature.
What is the Difference between paraffin oil and paraffin liquid?
Paraffin wax is a white or colorless soft solid that is used as a lubricant, when this is melted down it becomes a paraffin liquid. Paraffin oil is used in cosmetics and medical settings and is a highly refined mineral oil.
What paraffin become when heated?
When paraffin wax is heated, it melts and turns into a liquid state. Upon further heating, the liquid paraffin wax can begin to vaporize and produce fumes. If the temperature is too high, paraffin wax can catch fire.
Does mercury float on liquid paraffin?
No.
Does liquid paraffin evaporate?
yes
How should I seperate paraffin and water?
Separating paraffin (a type of wax) and water can be done through a process called "decantation" or "liquid-liquid separation" because paraffin and water do not mix
What is the purpose of determining the average density for each liquid in this experiment with different glassware?
to find the percentage of the relative error
