fordetermining point of ice,the thermometer should be kept
The apparatus used for determining the melting point will heat the sample at an appropriate rate. All you need to do is watch and note the point at which the sample melts, as should be demonstrated to you by your lab supervisor.
The melting point of lead is 327,46 0C.
Paraffin oil is nontoxic, noncorrosive and stable.
oil is used when we are determining the melting point of compound higher than 100 while for those compound which have melting point less then 100 we use water bath
Yes it si.

When determining the melting point or the freezing point of something....that is when they are used....
The melting point of lead is 327,46 0C.
The thermometer would melt
thermometer
it is because they were consistent at melting and boiling point
harder to separate
you will observe no difference in it.
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.

Boiling point- the temperature and pressure at which a liquid and a gas are in equilibrium. But also, it is very useful in determining the purity of a substance. If the melting point is known of the pure substance, than you can measure the melting point of what you've got and see if it matches. If the melting (or boiling) point is the same, than that is a good indication that the compound you have is what you think it is, and it is pure. If they are different from each other, that indicates that your compound is not pure.
