What else can I help you with?
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
What simple test can you do to determine if a given solid is pure or not?
One simple test to determine if a solid is pure is to measure its melting point. A pure substance will have a sharp melting point, while impurities will cause the melting point to be lower and more spread out. Comparing the measured melting point to the known melting point of the pure substance can help determine its purity.
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 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.
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 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.
Why is melting point of pure water 44 degree celsius?
The melting point of pure water is actually 0 degrees Celsius. At this temperature, water transitions from a solid (ice) to a liquid state. The value you mentioned (44 degrees Celsius) seems to be incorrect.
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.
What is true about the melting point and freezing point of water?
The melting point and freezing point of water is the same at 0 degrees Celsius (32 degrees Fahrenheit) under standard atmospheric pressure. This means that water will transition from solid to liquid (melting) or liquid to solid (freezing) at this temperature.
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
Freezing point of pure substance 21 degrees what is the melting point?
The melting point of a substance is the same as its freezing point in a closed system. Therefore, if the freezing point of a pure substance is 21 degrees Celsius, its melting point would also be 21 degrees Celsius.
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.
