Why does the temperatures stop falling at the freezing point?

Question

I know that the temperatures stop falling at the freezing point because the energy of the heat of fusion must be taken away (the liquid must turn solid or vice versa) before the temperature falls again, but exactly why? also, howabout the melting point? the temperature stops rising there too, why?

Answer 1

I believe you're referring to an experiment where you freeze water and you have the thermometer immersed in the mixture of ice and water. As water freezes it releases energy (the latent heat of fusion) which keeps the temperature constant until all the water has frozen, at which time the temperature will resume falling. Of course it's just the same thing when you are melting ice: energy goes into melting the ice, rather than raising the temperature of the mixture.

Answer 2

The temperature only stops falling at the freezing point when the devise is immersed in liquid, when the same thermometer is left out in the open it will indeed keep getting lower as the temperature falls, the same with the melting point.
So you're statement is not entirely true. If it were there would be no such thing as "below zero" or above any given figure.

Answer 3

The same answer in reverse.

A large amount of heat (the negative of the heat of fusion) must be absorbed by the material to break the molecules apart, from their solid structure into the more random and diffuse liquid structure. After all of the substance transitions from a solid to a liquid the temperature can rise again.

Answer 4

they don't contained in the united kingdom as antifreeze brokers are not to any extent further regarded in British or ecu criteria. Portland cement gadgets at particularly low temperatures and gadgets directly. daylight hours temperature must be above 40F and the mortar might want to no longer be laid on frozen surfaces. Nor might want to the cement be used if it has frozen in storage - it might want to be discarded. there'll, hence be some days of the year depending how harsh the wintry climate is even as bricklayers can't paintings. even as the temperatures are severe sufficient the bricklayer keeps the combination on the dry part and then even as it truly is placing covers it to dodge it from freezing with Hessian sacks topped with a water-resistant sheet.

Answer 5

It actually doesn't stop until it reaches the ultimate cold...no heat at all... as in frozen oxygen...-250 degree celcious. And its rising temperature doesn't stop until...Infinity?
