The boiling point of water is 212 degrees, most vehicles now days operate ftom 205 to 215. A 50% mix of distilled water and antifreeze will extend the the boiling point to 265 degrees at sea level. If you go up in elevation the boiling point will decrease, so make sure you have a known good or new radiator cap to prevent premature water boiling in higher elevations

Anything dissolved in water will lower the freezing point of the water. Alcohols such as propylene glycol and ethylene glycol are used as antifreeze in cars. They also elevate the boiling point and keep the car from boiling over when they get hot.

It will raise the boiling point. This why, for example, car radiators have a pressure cap. This causes a rise in the boiling point of the water and it is less likely to boil.

No, boiling water only kills the germs and bacteria in the water. It does not remove minerals. Use only distilled water in a car battery.

Yes, for many reasons, just a few of which are: water is a compound and blood is a mixture the water component of blood also has compounds dissolved in it (water-based solutions have higher boiling points than water itself...this is why the water/antifreeze solution in your car doesn't boil at 100ยฐ C).

you may mean hydroplaning, and it refers to the times were your car "skis" over the water causing you to have no control over anything your car does.

Most likely it is coolant getting to hot and boiling over, car is most likely overheating. Check for fluid under car, and temperature gauge.

I tell u exactly why that is try this yourself take boiling water on your stove. Get it to boiling temp and hold a thermometer above the steam and take a reading notice it is much lower and then drop the thermometer into the boiling water, much higher rite???? Big difference in measuring steam temperature and direct hot water.... Just like your coolant temprature sensor it has to be submerged in coolant to get true reading ..when in fact you are over heating basically cooking your engine its just that your sensor is just not able to detect that you are cause it is reading steam temprature which in no way good for any car to be that hot especially if it is alunimum eninge it can cause major damage. and that is the best answer to your question. Thank you n have a nice day

the boiling point of water depends on the surrounding air pressure. the boiling point of water in normal open conditions is 100 degrees centigrade , based on the standard atmospheric pressure of 1 BAR pressure . however if the pressure is increased the boiling point will increase . likewise at high altitudes on a mountain side, the boiling point will reduce to a lower level. imagine the insde of a car engine system and its components ; the water circulated is then cooled in a sealed system in a radiator , a certain amount of steam is created and increases the boiling point , within the sealed radiator,

Yes. The purpose of anti-freeze/coolant in twofold. It keeps the coolant from freezing and keeps the engine coolant from boiling over. Modern engines run at temperatures above the boiling point of water. Anti-freeze helps raise the boiling point above 212 degrees thus preventing overheating. Always add a 50/50 mix of the correct anti-freeze for your application and distilled water. Never use tap water and never run an engine without anti-freeze.

If the gauge is reading hot and the car is running normal temperatures, the water temperature sensor needs replaced.

Take off the radiator cap of the car. Start it up and watch the temp guage. when the car starts getting warm look in the radiator and see if you have water flowing. If not that is a sign it's bad. The other way is to take out the thermostat go inside and get some water boiling set the bottom of the thermostat in the boiling water, if it doesn't pop out then it is bad.

It's steam from boiling coolant (or water) coming out of the overflow hose connected to the top of the radiator just below the level of the cap.
