Lowering the freezing point simply means that you have done something to whatever you want to freeze (or don't want to freeze), so that a lower temperature is needed to make it freeze.
For instance, adding salt to water lowers it's freezing point (which is normally 32 degrees Fahrenheit).
That's why salting a sidewalk or roadway makes the ice melt under normal winter conditions.
You can also lower the freezing point of water by adding alcohol or propylene glycol (automotive antifreeze).
What else can I help you with?
When compared to pure water what will a 0.5 M solution of potassium chloride have a. lower boiling point b. lower freezing point c. higher capor pressure d. lower osmotic pressure?
b. lower freezing point A 0.5 M solution of potassium chloride will have a lower freezing point compared to pure water due to the presence of solute particles which disrupt the formation of ice crystals.
Does a lower Celsius number mean colder?
Yes, a lower Celsius number indicates a colder temperature. The Celsius scale is based on the freezing and boiling points of water, where 0°C is the freezing point and 100°C is the boiling point. as the number decreases, the temperature decreases.
Does antifreeze have a lower or higher freezing point than water?
Antifreeze has a lower freezing point than water, typically around -37 degrees Celsius (-34 degrees Fahrenheit), making it effective for preventing water from freezing in cold temperatures.
Freezing point is the point at which a liquid turns into a solid What effect can change the freezing point?
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.
Compared to the pure water an aqueous solution of calcium chloride has a?
Higher boiling point and a lower freezing point. These are called colligative properties. When a solute is put into solution with the solvent, there is a change in the vapor pressure, osmotic pressure, elevation of the boiling point, and depression of the freezing point.
Is the freezing point of ice cream lower or higher than the freezing point of water?
It is lower.
Which has the lower freezing point oxygen or ethanol?
Oxygen has a lower point.
What information is most useful to determine the solution that has a lower freezing point?
To determine which solution has a lower freezing point, you need the concentrations of solute in each solution and their respective properties (molal freezing point depression constants). The solution with the higher concentration of solute and lower molal freezing point depression constant will have the lower freezing point.
Can the freezing point be lower than its boiling point in a constant pressure?
At a constant pressure, the freezing point is always going to be lower than the boiling point.
What is the effect of adding p nitrotoluene to the freezing point of naphthalene?
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.
What is the effect of salt in boiling and freezing temperatures?
The freezing point is lower and the boiling point is higher.
How does the number of moles affect the freezing point?
Higher the concentration of the solute, lower is the freezing point.
When compared to pure water what will a 0.5 M solution of potassium chloride have a. lower boiling point b. lower freezing point c. higher capor pressure d. lower osmotic pressure?
b. lower freezing point A 0.5 M solution of potassium chloride will have a lower freezing point compared to pure water due to the presence of solute particles which disrupt the formation of ice crystals.
What causes a lower freezing point?
Salt.
Will NaCl's affect the freezing point of a solution make the freezing point increase?
No, adding NaCl to a solution will actually lower the freezing point of the solution. This is because the presence of dissolved ions from the salt disrupts the formation of ice crystals, causing the freezing point to decrease.
Effects on freezing point when alum is dissolve in water?
The freezing point will be lower than water with nothing dissolved in it.
Does freezing lower the temp?
That's the definition of freezing. It means to lower the temperature of whatever is being frozen below the freezing point (32C for water).
