What are the boiling and melting point's of salty water?
That depends on how much salt is dissolved in the water. Generally, the boiling point will be higher than for pure water, and the melting point will be lower than for pure water.
When ethylene glycol is added to water the melting point of water is?
Ethylene glycol is antifreeze. The mixture has a lower melting point than pure water.
What is the simple physical test to show that a sample of water is pure?
A scientific test you do on water similar to a chemical test
Which test or observation can be used to show that a sample of glucose is pure?
You could test its melting point, since pure glucose has a known melting point of 146oC.
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
How do you think the melting point of salt water compares to that of pure water?
The melting point of salt water is even lower than pure water.
What are the boiling and melting point's of salty water?
That depends on how much salt is dissolved in the water. Generally, the boiling point will be higher than for pure water, and the melting point will be lower than for pure water.
What is true about the melting point and freezing point of water?
At standard pressure the melting (freezing) point of pure water is 0 0C.
What is the melting point of pure matter distilled water?
The melting point of ultrapure water is 0 0C at 1 atm.
When ethylene glycol is added to water the melting point of water is?
Ethylene glycol is antifreeze. The mixture has a lower melting point than pure water.
What three standard points define the common temperature scales?
Absolute zero, melting/freezing point of pure water, and boiling point of pure water.
Which is colder frozen water or frozen salt water at melting points?
The freezing point of salted water is lower compared with the freezing point of pure water. So when melting frozen salt water is colder.
What is the name of the line marked 0 degrees Celsius?
It is the melting point of pure ice and the freezing point of pure water under standard pressure.
Freezing point of pure substance 21 degrees what is the melting point?
The melting point would also be 21 degrees because the freezing point and melting point of a pure substance is exactly the same.
What is the simple physical test to show that a sample of water is pure?
A scientific test you do on water similar to a chemical test
How is the centigrade scale derived?
The centigrade scale is based on the melting and boiling points of pure water at 1 atmosphere of pressure. 0oC is the melting point and 100oC is the boiling point.
What is the point where a pure solid change to a liquid?
melting point
