The quantitative observations are the temperatures taken at specific intervals until the salt solution freezes, or until the temperature no longer changes.
The freezing point is a quantitative property because it can be measured and expressed as a specific temperature at which a substance changes from a liquid to a solid state. This value is characteristic of the substance and can be used to identify or classify it.
The freezing point is lower and the boiling point is higher.
yes
It chances the boiling point of the water, and it changes the freezing point of the water
Changing the pressure can affect the freezing point of a substance. Generally, an increase in pressure will lower the freezing point, while a decrease in pressure will raise the freezing point. The presence of solutes or impurities in the liquid can also change the freezing point.
Adding p-nitrotoluene to naphthalene will lower the freezing point of the mixture. This is due to the phenomenon of freezing point depression, where the presence of a solute lowers the freezing point of the solvent. The greater the concentration of the solute in the solvent, the lower the freezing point will be.
This depends on the freezing point.
it lowers the freezing point of the water
If the water contain impurities the freezing point is lowered.
boiling point is increased and freezing point is decreased
Salt increases the boiling point of water and lowers its freezing point.
Salt mixes with the water raising it's freezing temperature above normal.
