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.
Which has a higher freezing point a 20 percent salt solution or pure water?
Pure water has a higher freezing point than 20% salt water.
The freezing point of pure is?
zero degrees Celsius.
Is the freezing point of a pure solvent a plateau or a continuous downward trend?
The freezing point of a pure solvent is a plateau. As the solvent cools, its temperature decreases until it reaches its freezing point, at which point the temperature remains constant until all of the solvent is frozen.
What is the freezing point of pure water on Celsius scale is?
zero
What is the freezing point of an aqueous 2.85 m sodium hydroxide NaOH solution The freezing point of pure water is 0.0ºC and Kf of pure water is -1.86ºC m?
-10.6 Celsius
Is 32 in degrees Fahrenheit?
32ºF (or 0ºC) is the freezing point of pure water.
Is the melting point the same teperature as the freezing point for a substance?
Yes, when the substance is pure
When a solute is added to a solvent the freezing point of solutions is?
The freezing point is lowered.
What is the freezing point of sea water and pure water?
the sea water contains more salt. the pure water do not contain salt. the density of sea water is more than density of pure water. as there is more salt in sea water it is corrosive against the metals like aluminium. the pure water is not corrosive in nature. sea water is harmful for drinking. pure water is good for drinking.
Constant freezing point of acetone?
The freezing point of acetone at sea level is -94.7 C, -138.46 F, 178.45 k.
What is the freezing point for very pure water?
0 degrees Celsius
