What else can I help you with?
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
Explain why the boiling point and the melting point can be used to help identify substances?
100 degrees mate. 100 degrees Celsius is the boiling point for pure water at 1atm or sea level. The boiling point is useful in identifying chemical compounds. Chemical compounds have different boiling points that are specific to it' s chemical composition. If you know what the boiling point or melting point is you can also tell if your compound is pure, as any impurities will change these.
What information about the compound is not part of the chemical formula?
The information that isn't given in the formula is that it doesn't tell you the position of the atoms.
When ice melts why can you tell there is not a chemical change?
Melting is not a chemical change because the chemical formula of water remain unchanged.
What temp does water change from a solid to a liqid?
I believe ice will start melting as soon as the temperature goes above 0 deg C. ===== It also depends on the pressure. At 1 atm, it will start melting at 0.0 °C. But at a pressure of 2.2 GPa it won't melt until you get to almost 82 °C.
How can you tell that the melting of ice cube is a physical change?
You could test the resulting liquid by determining its boiling point and melting point. If they are the same as the boiling and melting points for water, then it is probably water and a physical change rather than a chemical change has occurred.
Could you tell me 3 examples from everyday life which show the affect of pressure and impurities on the melting and boiling points?
hey i really need help, can u answer the Question

What baking equipment can tell when water is boiling?
lol wow you dont need a piece of equipment to tell when water is boiling... you just watch the water as it heats up and when it starts to bubble its boiling... Ta -dah!
If more than one phase of water is present what does it tell you about the temperature?
The temperature will be either the boiling point (if liquid and vapor is present) or it will be the melting/freezing point (if liquid and ice is present)
Is the boiling point of water higher than the boiling point of water?
physiological answers tell us that In neurology water may be boiling at a lower substantial rate then non water water.
How can you tell that melting boiling dissolving are physical changes?
The physical and chemical properties, and chemical composition, are not changed after a physical change.
How can you determine if water is boiling?
Water is boiling when it reaches a temperature of 212 degrees Fahrenheit (100 degrees Celsius) at sea level. You can tell water is boiling by seeing bubbles forming and rising to the surface.

How can you tell a pure substance from a mature by its boiling point?
take water for example, if water boils at 100 degrees Celsius then it is pure. if the boiling temperature turns out to be higher or lower (most of the time it is higher) then a substance is impure. salt water boils at 102.8 degrees Celsius.
Did salt and sugar affect the boiling temperature of water exactly the same?
yes, but i couldn't tell you the mechanics of it.
