Solids have varying temperatures at which they melt into a liquid. Experiment with chocolate, wax or butter, record, which has the lowest and highest temperature when it melts.
The purpose is the homogenization of the sample temperature.
The melting point is 302.9146 K (29.7646°C, 85.5763°F) The boiling point is 2477 k (2204 °c, 3999 °f) Edit: The boiling temperature for gallium is quoted elsewhere as 2403°c. See discussion section.
The melting point is independent of the quantity. What changes is the amount of heat which must be supplied.
1) Experiment. 2) Ask the question on here. "What is the melting point of sugar?" *)I'll save you the trouble, though. The melting point of Table sugar (sucrose)= around 366.8°F or 186°C
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.
A melting point under the temperature of the experiment.
To prove that glucose does not raise the melting point of stearic acid, conduct a melting point analysis of stearic acid alone and stearic acid mixed with glucose. If the melting point of the mixture is the same as that of stearic acid alone, it indicates that the presence of glucose does not affect the melting point of stearic acid. This experiment can help demonstrate that glucose does not raise the melting point of stearic acid.

The purpose is the homogenization of the sample temperature.
The flat portion of the temperature-time graph during the melting point experiment indicates that the substance is undergoing a phase change. As heat is being absorbed to break the intermolecular bonds and transform the solid into a liquid, the temperature remains constant until all of the substance has melted.
it's -0000 degreee calcius
The melting point is 302.9146 K (29.7646°C, 85.5763°F) The boiling point is 2477 k (2204 °c, 3999 °f) Edit: The boiling temperature for gallium is quoted elsewhere as 2403°c. See discussion section.
This is the melting point.
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.
The melting point is independent of the quantity. What changes is the amount of heat which must be supplied.
The discussion for experiment of the microscope has focused on the many uses of the microscope. The discussion also goes into depth regarding the many techniques of use.
Discussion follows your main topic sentence of your results from your experiment. In the discussion, you describe the hypothesis you were trying to prove with the experiment, bring up any literature that supports your hypothesis - or not - and what happened during the experiment. Be sure to include how you set up the experiment.
