What else can I help you with?
What happens when the temperature stays the same in a melting curve?
During melting the temperature remain constant if it was achieved the melting point.
What happens if boiling point is higher than melting point?
The boiling point is always higher than the melting point.
How can melting point and boiling point determination be used in identifying and or characterizing unknown compounds?
Melting point and boiling point determination can help in identifying unknown compounds by comparing the experimental values with known values in databases. A match can indicate the compound's identity. Additionally, the range of melting point and boiling point can provide information on the purity and molecular structure of the compound.
What happens to the temperature of a solid at its melting point when heated?
The intermolecular forces of attraction in the solid decreases as it is heated and the solid melts (solid converts to liquid) at its melting point.
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.

What happens to neon during melting point?
There are a number of things that could happen to neon while it is at its melting point. It could melt.
Why is it misleading to identify a solid compound just from a lone melting determination?
Identifying a compound based solely on its melting point is misleading because different compounds can have the same melting point. Additional tests, such as spectroscopic analysis or chromatography, are required to accurately determine the compound's identity. A single melting point determination is not sufficient as it could lead to a wrong conclusion about the compound present.
What happens if boiling point is higher than melting point?
The boiling point is always higher than the melting point.

What happens in the melting point of ice?
it evaporates
Why is the melting point determination not used to find the melting point of inorganic compounds?
Melting point determination is not commonly used for inorganic compounds because many inorganic compounds have high melting points that are difficult to determine accurately using conventional methods, which can involve significant heating requirements and specialized equipment. Inorganic compounds can also have complex melting behavior, such as decomposition or phase transitions, that make determination of a precise melting point challenging. Analytical techniques like differential scanning calorimetry or thermogravimetric analysis are often more suitable for studying the thermal properties of inorganic compounds.
Is the use of stirrer necessary during heating while determining the melting point of ice in laboratory?
Yes, using a stirrer is necessary during heating to ensure uniform temperature distribution. Without stirring, the temperature might vary within the sample, leading to inaccurate melting point determination. Stirring helps to achieve equilibrium and ensures an accurate measurement of the melting point of ice.
Why should samples for melting point determination be finely powdered?
Samples should be finely powdered for melting point determination to ensure uniform heating and accurate results. Fine powder allows for even distribution of heat throughout the sample, leading to consistent melting behavior and precise measurement of the melting point. Unevenly sized particles can result in inaccurate readings and can affect the repeatability of the experiment.
What happens to the temperature of a solid at its melting point when heated?
