What else can I help you with?
If a student wishes to test the hypothesis that adding antifreeze to water lowers the freezing point of water. What would be the dependent (responding) variable?
The dependent (responding) variable in this experiment would be the freezing point of the water-antifreeze mixture. This is because the freezing point is what the student measures and observes in response to varying amounts of antifreeze added to the water. Changes in the freezing point will indicate how the addition of antifreeze affects the freezing characteristics of the water.
What happens to water when antifreeze is added to it?
When antifreeze is added to water, it lowers the freezing point and raises the boiling point of the mixture. This helps prevent the water from freezing in cold temperatures and boiling in hot temperatures, making it more suitable for use as engine coolant.
When ethylene glycol is added to water the boiling point of water is?
When ethylene glycol is added to water, the boiling point of the resulting solution increases. Ethylene glycol acts as an antifreeze, raising the boiling point and lowering the freezing point of water.
Why in chemical terms is anti-freeze added to car windscreen wash?
Antifreeze is added to car windscreen wash to lower the freezing point of the liquid. This prevents the solution from freezing in cold temperatures, which can damage the system and obstruct vision during driving. Antifreeze typically contains chemicals like ethylene glycol or propylene glycol that are effective in preventing freezing.
When ethylene glycol is added to water the melting point of water is?
Ethylene glycol is antifreeze. The mixture has a lower melting point than pure water.
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 happens to water when antifreeze is added to it?
When antifreeze is added to water, it lowers the freezing point and raises the boiling point of the mixture. This helps prevent the water from freezing in cold temperatures and boiling in hot temperatures, making it more suitable for use as engine coolant.
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 does adding antifreeze to water do?
It lowers the freezing point.
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.
When ethylene glycol is added to water the boiling point of water is?
When ethylene glycol is added to water, the boiling point of the resulting solution increases. Ethylene glycol acts as an antifreeze, raising the boiling point and lowering the freezing point of water.
Can check engine light go on w low antifreeze?
Doubtful !... The antifreeze is added to the radiator - to keep the water above freezing point. There is no way of the engine knowing how much antifreeze is circulating.
How does antifreeze keep the water in your radiator from freezing and overheating?
It changes the freezing and boiling point.
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.
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.
How does an antifreeze prevent freezing in cold months and overheating and boiling?
It lowers the freezing point and raises the boiling point of water.
Which compound can be used as the antifreeze in cars radiators by mixing with water?
Any substance that lowers the freezing point of water such as ethylene glycol or propylene glycol which are commonly added to water
