Do all substances have their own boiling point and freezing point?
Yes, all substances have unique boiling and freezing points that are determined by their chemical composition and properties. These points represent the temperature at which a substance changes its state from liquid to gas (boiling point) or from liquid to solid (freezing point).
What is the boiling point and the freezing point of neon?
Living on a water table like this is never an easy situation. There are a few different options that would all definitely suffice for this particular occasion, though I would recommend vinyl: http://knol.google.com/k/new-basement-flooring-options#
What is the melting point of copper pipe?
The melting point of copper is approximately 1,984°F (1,085°C), but this can vary slightly depending on the specific composition of the copper alloy used in the pipe. It is important to note that the melting point of copper pipe should never be reached during regular use, as it could lead to structural failure and potential safety hazards.
Why should melting point tests never be repeated on the same sample?
Once a sample has been melted, it may have decomposed slightly. Contamination with a decomposed product will change the MP of the sample, so a fresh sample must always be used for each new test.
What is the melting point of sandstone?
the melting point of sandstone is approximately 1300.68754893C' The melting point of sandstone depends on its density, or hardness. Sandstone varies greatly in chemical composition, ranging across different properties, from sand so loosely compacted that it crumbles in the hand, to stone so hard it was once used to mill grain into flour. The higher the density of sandstone, the higher the melting point. Suffice it to say that sandstone, no matter how dense, is never used to make the bricks of a pottery kiln, even though that would be a very inexpensive stone to use, because the stone is not reliable at the high temperatures some kilns sometimes require. For instance, bright white hot, the temperature required to fire stoneware, requires a heat of at least 1300 degrees Celsius, or about 2380 Fahrenheit, for several hours. That much heat would almost certainly, and permanently, damage a kiln made of even the hardest sandstone. For the same reason, sandstone is no longer acceptable in the building code of most developed nations for the brick of a chimney.
Why would a liquid have two different boiling points?
possibly if it has been contaminated by other substances (as compared to original boiling point - it seems as though it has 2 different boiling points) things such as sodium chloride (table salt) raise the boiling point of water and lower its melting point note though that a pure liquid can never have 2 different boiling points - the boiling point is a property of a a liquid and will never change no matter what. alternatively if the fluid concerned is a mix of 2 different liquids (eg. alcohol mixed in water) the liquid with the lower boiling point (eg. alcohol) will boil off first, then the remaining fluid will continue heating up until the 2nd boiling point is reached (eg. of water). thus the fluid seems to boil at 2 different temperatures
What is helium's melting or boiling point?
Helium doesnt have a melting point as it will never form solid.
Do all substances have their own boiling point and freezing point?
Yes, all substances have unique boiling and freezing points that are determined by their chemical composition and properties. These points represent the temperature at which a substance changes its state from liquid to gas (boiling point) or from liquid to solid (freezing point).
Are ice melts chemical reactions?
No, melting is never chemical! Neither is boiling, freezing, etc. Those are changes of 'the STATE of matter' and purely physical.
How does the melting point of the crude sample compare with that of the purified sample?
An impure sample will have a lower melting point, and will also have wider melting point range than that of a pure sample of the same substance. a sharp melting point range can also indicate a eutectic mixture
What is the property that is a quality of a substance that never changes and can be used to indentify the substance?
A quality of a substance that never changes is one of the reasons why density is a characteristic property
What is the melting point for helium in kelvin?
helium is a gas so it doesnt meltThe melting point of Helium is
Why does boiling oil bubble?
Hmmm, I have never seen or heard of hot oil boiling.
What would the temperature of a pot of water be if you continued heating for 10 minutes after it had already started boiling?
If the water is actively boiling, it is never more than 100 degrees Celsius (212°F).When water is not boiling (because of pressure or lack of nucleation points), it can become hotter than 100°C, a process known as superheating.

How would you know that the boiling rocks boil at same teperature each time?
By measuring the temperature of the rocks, and recording what temperature they are at when they start boiling. Also, through the years of chemistry, we've determined that each substance has properties that never change, such as boiling point, and melting point. Ice for instance melts into water above 32 F, or 0 C and boils at 212 F or 100 C. Below this range, water is a solid, (ice) and under normal conditions water will not heat above this range. The boiling point is the point at which as much energy is being put into it, the same amount will be released through boiling. The same can be said for the minerals that make up rocks, (except that the melting and boiling points on rocks is much hotter) Some conditions can change the boiling point of a substance. High pressure means a higher temperature will be needed to cause boiling (this is how a pressure cooker works) Low pressure will need a lower temperature to reach boiling.
When does two points that are collinear meet?
Never. They are points on the same line. *------*
