What else can I help you with?
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.
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 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.
Freezing point in Everest?
The freezing point on Mount Everest varies depending on altitude, but on average it hovers around -18°C (-0.4°F) at the summit. However, temperatures can drop much lower depending on weather conditions. At higher elevations, where atmospheric pressure is lower, water can freeze at a higher temperature.
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.
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.
Does antifreeze you put in a car radiator have a lower or higher freezing point than water?
Antifreeze, typically made from ethylene glycol or propylene glycol, has a lower freezing point than water. This property allows it to prevent the coolant in a car radiator from freezing in cold temperatures, which helps maintain engine performance and prevents damage. When mixed with water, antifreeze lowers the overall freezing point of the solution, providing effective protection against freezing.
Is the freezing point of ice cream lower or higher than the freezing point of water?
It is lower.
What colligative property is responsible for antifreeze?
The colligative property responsible for antifreeze is freezing point depression. Adding antifreeze (such as ethylene glycol) to water lowers the freezing point of the solution, preventing the liquid from freezing at lower temperatures.
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.
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.
How can antifreeze be used in a toilet to prevent freezing?
Antifreeze can be added to a toilet to prevent freezing by mixing it with water in the tank or bowl. This helps lower the freezing point of the water, preventing it from solidifying in cold temperatures.
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.
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.
