A thermometer should be immersed in the ice water mixture in order to accurately determine the melting point of ice. This ensures that the thermometer is in direct contact with the substance being measured and will provide a precise reading of when the ice starts to melt.

How a thermometer can be used to check the purity of a metal?

A thermometer can be used to check the purity of a metal by measuring its melting or freezing point. Impurities in a metal can alter its melting point, so a pure metal should have a specific and consistent melting point. By comparing the measured melting point with the known melting point of the pure metal, the level of purity can be evaluated.


How fast do you heat the sample when determining a melting point?

The rate of heating when determining a melting point typically ranges from 1-10 degrees Celsius per minute, with a common standard being 2 degrees Celsius per minute. This rate ensures that the sample is heated uniformly and allows for accurate observation of the melting point.


What is the sub discipline of determining the melting point of lead?

Determining the melting point of lead falls under the subdiscipline of materials science, specifically in the field of physical metallurgy or thermodynamics. Scientists use techniques such as differential scanning calorimetry or thermal analysis to precisely measure the melting point of lead.


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 do you use pure ice in determining a lower fixed point of a thermometer?

Pure ice is used to determine a lower fixed point of a thermometer because it is a well-defined substance with a known melting point of 0°C under standard atmospheric pressure. This makes it a reliable reference point for calibrating and verifying the accuracy of a thermometer.

The temperature at which a substance changes from a liquid to a solid is the?

This is called the melting point, and the temperature is different for every material. For pure water, it is zero degrees Celsius, or 32 degrees Fahrenheit. Determining the melting point of any material is an important clue to determining what the material is.

What is difference between melting point and drop melting point?

The melting point is the temperature at which a solid substance transitions to a liquid state. The drop melting point is a method of determining the melting point where a small amount of the substance is heated until it melts and then allowed to drop onto a solid surface to observe the melting point. Drop melting point is often used when the substance being tested has a high melting point or when observing the melting process is critical.


If you heat too fast when determining melting point will you observe a lower or higher melting point than true value?

If you heat too fast when determining melting point, you may observe a lower melting point than the true value. This is because rapid heating can lead to the formation of a supersaturated solution, causing the melting point to appear lower due to impurities not having enough time to properly dissolve or crystallize.
