What three things control wheather or not a rock will melt?
The three main factors that control whether or not a rock will melt are temperature, pressure, and the presence of fluids (such as water or gases). Increasing temperature and decreasing pressure are the most common ways to induce melting in rocks, while the presence of fluids can lower the melting point of certain minerals within the rock.
What are two ways that you could tell the difference between pure water and salt water?
Taste Smell Melting Point Boiling Point Density Residue after it evaporates
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 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.
How does the composition of magma affect the temperature at which it solidifies?
Magma consists of molten rocks and metals. The composition can vary based on presence of water, metals with different melting points, and such.
What are two ways you can identify a physical property?
You can identify a physical property by observing and measuring characteristics such as color, shape, size, or density. Another way is to perform various tests or experiments to determine properties like melting point, boiling point, or conductivity.
What are some ways of melting NaCl?
Rising the temperature to 801 0C sodium chloride is melted.

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.

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 only way to change dew point?
Changing the air temperature or humidity level are the only ways to change the dew point. If the temperature or humidity increases, the dew point will also increase. Conversely, if the temperature or humidity decreases, the dew point will decrease.
What are similarities between Kelvin and Fahrenheit?
1.they both are the scales used to measure the temperature in a thermometer . 2.the reference points taken in these two scales are the melting point of ice and the boiling point of water. 3.if we want to convert one scale from the other they both has 5/9
