Much lower or else there would be little point in using as antifreeze

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?
a lower freezing point
Does salt affect the temperature of water -boiling point - freezing point?
i would opt for the Freezing point. salt decreases the freezing point of water. so if water would normally freeze at 0C, saltwater would freeze at -3C.
Does methanol lower the freezing point?
Methanol will freeze at negative 143 (Fahrenheit)/ negative 97 (Celsius). If it is added to water (freezing point of 32*F/0*C) then it will make the water freeze at a lower temperature. So yes, methanol will lower the freezing point of any liquid that freezes at a higher temperature than methanol. But methanol cannot lower the freezing point of any liquid that will still be liquid at -143*F/-97*C.
What do lower the freezing point mean?
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).
How does the presence of a solute affect the freezing and boiling points of a solvent?
They usually lower freezing points, think antifreeze. And salt water freezes at a lower temp than fresh, that is why they put salt on ice. And they raise boiling points, think salt in water when making spaghetti. Or, again antifreeze.
Why does antifreeze boil faster than water?
It does NOT boil faster than water. It has higher boiling point AND lower freezing point. - Antifreeze boils at about 197 c.
Does antifreeze boil at a lower temperatures than pure water?
The mixture of the two liquids (water and antifreeze ethylene glycol))has a higher boiling point and lower freezing point than water alone.
Is the freezing point of ice cream lower or higher than the freezing point of water?
It is lower.
What is antifreeze?
Antifreeze is a substance such as glycol which is used to lower the freezing point of water, and is used as an additive in the radiators of motorcars.
If you add salt to water does it make the freezing temperature higher or lower?
It make the boiling point higher, and the freezing point lower.
What is a sentence for the word antifreeze?
A sentence for the word antifreeze may be, " What is the best antifreeze to use in drinking water?" Antifreeze is a liquid which is used to lower the freezing point.
How does the number of moles affect the freezing point?
Higher the concentration of the solute, lower is the freezing point.
What is the effect of salt in boiling and freezing temperatures?
The freezing point is lower and the boiling point is higher.
What effect does antifreeze have on the melting point of ice?
Antifreeze decreases the freezing point of ice so that it melts at lower temperatures also.
Which facts about the use of antifreeze illustrates a rule that governs the physical world?
Antifreeze keeps water from freezing when it is cold out. The antifreeze liquid lowers the freezing point of the water. Even when freezing (to a slurry) it does not form solid ice that can rupture the radiator. The antifreeze combines the water to form a liquid with a lower freezing point than water alone.
Is antifreeze added to car radiators to lower the freezing point of water?
Yes. The antifreeze/coolant also raises the boiling point and has lubricant and anti corrosive properties.
What happends when antifreeze is mixed with water?
Nothing, you have a solution of antifreeze. However if you then cool the solution the freezing point will be lower than that of pure water.
