How would you determine the purity of the solid crystals in crystallization?
One of the easier and more reliable ways to check if a solid compound is pure after re-crystallization is to check its melting point. Impurities will always lower the melting point of a sample, and the more impure, the lower the melting point will be. By checking the melting point of your sample with a reference value from a book or reliable internet source, it can be determined exactly how impure the sample is. If perhaps your compound is unknown, and thus are unable to obtain a reference value, you could obtain melting point of the sample, and then re-crystallize a few more times, obtaining a new melting point each time, until it is unchanged by re-crystallizing. This will of course decrease your yield, but if there is little fluctuation in your series of melting points, you can be sure you have a relatively pure sample.

What is ZFC-FC?
Zero Field Cooling - Field Cooling Measuring an effect from a field in the two following ways: ZFC- Applying the field at a relatively low temperature compared to a characteristic temperature and continuously measuring the effects of the field as you raise the temperature to a level well above the characteristic level. FC - Applying the field at a relatively high temperature compared to a characteristic temperature and continuously measuring the effects of the field as you lower the temperature to a level well below the characteristic level. FC can be thought of as the reverse process to ZFC. If the effect you're measuring doesn't reverse using ZFC-FC, then you have something interesting on your hands.
What is the melting and boiling point of metals?
Which metal needs to be specified. Look in a Chemistry book or reference book. All metals have their own melting and boiling points - that's one of the ways we identify which metal the item is made of.
How does temperature change in objects?
yes. i am doing a report on it now and i am finding out many ways temperature affects objects. just think about the states of matter. how does a solid turn into a liquid? temperature. an example of this is melting ice cream :) yes. i am doing a report on it now and i am finding out many ways temperature affects objects. just think about the states of matter. how does a solid turn into a liquid? temperature. an example of this is melting ice cream :)
What are some ways of melting NaCl?
Rising the temperature to 801 0C sodium chloride is melted.

How do you liquidify powdered sodium hydroxide?
Two ways: (i) heat it to the melting point of Sodium Hydroxide OR (ii) dissolve it in water.

Which physical properties could be the basis for separating the metals that are mixed to make an alloy 1 color2 melting point 3atomic mass 4atomic number?
To physically separate them you'd have to use melting point. Heat the mixture up and the element with the lowest melting point will become liquid first. None of the others are methods of separating components, just ways of describing them.
What are the two ways of measuring for accuracy?
Two ways of measuring for accuracy is by using a food scale or by measuring tools. This way, the recipe can result as expected.

How do you dry oxygen?
There are a couple of ways of drying oxygen, the first it to cool it past its boiling point, then past its melting point. This gives you a solid block of oxygen, though the temperature has to be maintained to keep it solid. The second way is to pressurize it, with enough pressure oxygen will be compacted into a solid, though again the pressure has to be kept up or it will vaporise again.
