Freezing Definition and 161 Threads

The last few days have been very cold and when I come back to my car, water has condensated (to solid phase) in the windows. I have noted that the ice seems to form in lines that cross each other (forming seemingly random patterns made of almost perfectly straight lines) Of course there is...

im confused... we add rock salt to ice cream to lower freezing point. but how dose that help in making ice cream? and when we add salt to the snow on the streets in order to melt them, dosent that also lowers the freezing point? dosent that makes the snow harder to melt? thanks

What kinds of tanks are capable of resisting these types of pressures? (30,000 psi). I can't find any tanks that can. I would assume extremely thick steel could, but I can't find any specific tanks/containers in production that can. What naturally occurring rocks are able to not crack when...

How many grams of urea (MW = 60.056 g/mol) would have to be dissolved in 115.0 grams of water to lower the freezing point by 1.60 degrees celsius? Equation for freezing point Tf= Kf x Cm Kf= 1.858 Cm= molality of solute in kg please help, iam getting the same answer

I heard if you put a wasp quickly in a freezer then thaw it some time later, it comes bacl to life. I am guessing the wasp would on average live as long as it would if it had not been frozen?

Here's a question I've been thinking about for a while; maybe you guys could provide some guidance. If the air temperature is below 0 degrees Celsius, the water at the surface freezes to form ice, right. Now the question I have is: why doesn't freezing occur throughout the entire volume of...

There is a scene in the movie The Day After Tomorrow in which the temperature over Scotland rapidly drops to -150 F. The fuel lines in three helicopters freeze almost instantly and the helicopters fall out of the sky. That didn't seem too plausible to me. If any of you work with such fuel lines...

How much outward force is applied when liquid H2O freezes, turning into ice?

when an ice berg freezes in salt water, the ice is actually pure water because the freezing water kind of pushes the salt out. so why does the suger in koolaid freeze with the water. i asked my chemistry teacher and he looked for the answer but he doesn't know why. this may seem like a stupid...

How many pounds of pressure are exerted by a gallon of freezing water?

this is going to sound like an odd question, but which element has its boiling point and its freezing point closest together? by which i mean, which transitions through the phases the fastest?
