What else can I help you with?
Do proteins have definite melting points?
Different proteins have different melting points.
When do scientists make measurements?
Scientists make measurements during experiments or observations to collect data and analyze their findings. Measurements help scientists quantify variables, test hypotheses, and draw conclusions about the natural world. By accurately measuring quantities such as mass, volume, temperature, and time, scientists can better understand the processes and interactions in their field of study.
Are melting points of molecular substances higher than those of ionic substance?
Ionic substances have higher melting points.
If a substance forms crystals when it solidifies its melting and freezing points are the same?
Melting and freezing points are identical.
For what two reasons are the melting points routinely used?
Melting points are routinely used to determine the purity of a substance. Impurities often lower the melting point of a substance, so a lower-than-expected melting point can indicate the presence of impurities. Melting points are also used to identify unknown substances by comparing their melting points to established values.
Why do you need to know different temperatures as scientists?
the person which is aware of chemistry should know the simplest temperature as melting and boiling points of water i-e o and 100 degree centigrade.......if u will aware of these temperatures as the scientists know it will help u in studies.....
How can the melting and boiling point help you identify it?
Melting and boiling points are physical properties unique to each substance, so knowing these values can help identify a substance. By comparing the observed melting and boiling points of an unknown substance to known values in a database, you can narrow down the possible identities of the substance. Substances with similar melting and boiling points are more likely to be the same compound.
Which ions have high melting points?
positive ions have high melting points
Do proteins have definite melting points?
Different proteins have different melting points.
Compared with the melting points of ionic compounds the melting points of molecular solids tend to be .?
Ionic compounds have a higher melting point.
How do you identify solids at melting or boiling points?
Melting and boiling points are different for each compound or element.
Do elements compounds and mixtures have fix melting and boiling point?
Elements have fixed melting and boiling points, while compounds have varying melting and boiling points depending on their composition. Mixtures do not have fixed melting and boiling points, as they are composed of multiple substances which each have their own individual melting and boiling points.
Explain why there is this pattern in melting points for francium?
The melting point of francium is not measured, only supposed by comparison with the melting points of the other alkali metals.
What are the melting points for iron?
1535 degree melting of iron
Where are the freezing points and melting points of gold?
1064.18

Why can the boiling point and the melting point be used to help identify a substance?
The boiling and melting points are almost unique to individual substances. If it should happen that two possible substances have the same melting point, they can still be identified by the method of mixed melting points. If substances A and B have the same melting point and you mix them, the mixture will melt belowthe tabulated temperature. Thus if you mix your unknown with a sample of what you think it is, if you are right it will still melt sharply at the expected temperature, but if you are wrong it will melt gradually and at a lower temperature.
