https://padlet.com/pauloberoi2/pik5qkwdxbawndes Why did the hot water cup or cold water cup freeze first in your opinion? en-us 2020-06-27 20:09:43 UTC 2020-07-10 17:57:09 UTC hello@padlet.com 348890013 https://padlet.com/pauloberoi2/pik5qkwdxbawndes/wish/648545007 I think that the cold water cup would freeze first because the hot water cup has to cool down before it can freeze because hot things can't freeze.  The cold cup is already cold therefore it will take less time to freeze.

First, the hot water has to cool down. While the hot water is cooling down. the cold water will already be freezing because it was cold cold beforehand causing the cold water to freeze in less time the the hot water.]]> 2020-07-06 18:52:37 UTC https://padlet.com/pauloberoi2/pik5qkwdxbawndes/wish/648562868 https://padlet.com/pauloberoi2/pik5qkwdxbawndes/wish/648568948 The hot water froze first but I generally don't know why. I just read that this is because of something called The Mpemba effect. It is basically an observation of the fact that hot water freezes faster than cold water. This could be because warm water evaporates faster and since this is an endothermic process, it makes the water freeze quicker. Another could be that warm containers make better thermal contact with the refrigerator. This is just what I read and it did seemed that the hot water did freeze faster]]> 2020-07-06 19:01:43 UTC https://padlet.com/pauloberoi2/pik5qkwdxbawndes/wish/648568948 https://padlet.com/pauloberoi2/pik5qkwdxbawndes/wish/649364891 Imagine throwing hot water into the freezing winter air, it would freeze, become snow. Though this does not occur to cold water. Hot water is more dense, solid, than cold water so it basically is freezing as it cools down. Therefore resulting in faster results than cold water.

It has to Cool down first and that will probably take a bit of time but then I tried it and read about it and apparently hot water freezes faster then cold water and that is called the Mpemba effect]]> 2020-07-07 17:39:22 UTC https://padlet.com/pauloberoi2/pik5qkwdxbawndes/wish/649397066 https://padlet.com/pauloberoi2/pik5qkwdxbawndes/wish/651155983 I think the cold water will freeze first because the hot water is obviously hotter. The hot water has to cool down first in order for it to freeze there taking more time.]]> 2020-07-09 16:56:20 UTC https://padlet.com/pauloberoi2/pik5qkwdxbawndes/wish/651155983 https://padlet.com/pauloberoi2/pik5qkwdxbawndes/wish/651166622 The hot water would freeze first because if you put it in the freezer then they are transitioning to becoming cold like ice. So since the water is hot it transitions faster then cold water because it is hot, just like when your washing your hands and the water is hot but then it turns to cold much faster then if the water is already cold.]]> 2020-07-09 17:11:55 UTC https://padlet.com/pauloberoi2/pik5qkwdxbawndes/wish/651166622 https://padlet.com/pauloberoi2/pik5qkwdxbawndes/wish/651178069 If I were to make an assumption I would say that the cold water would freeze before the hot water due to it already being cold and the particles moving slower than the hot water.

But for the hot water, it will take a longer time because first, it needs to cool it down first, and then it needs to freeze it, so a cup of a hot water basically has 2 steps before it can freeze completely and for the cold water, it only has one step before it completely freezes. In conclusion, cold water will freeze first.]]> 2020-07-09 18:46:10 UTC https://padlet.com/pauloberoi2/pik5qkwdxbawndes/wish/651235289 348829656 https://padlet.com/pauloberoi2/pik5qkwdxbawndes/wish/651261027 it took me 15 min to freeze the cold water and 20 min for the hot water. because the cold water, as you know, is already pretty cold already so it'll take less time, but hot water still needs to decrease.]]> 2020-07-09 19:25:02 UTC https://padlet.com/pauloberoi2/pik5qkwdxbawndes/wish/651261027 https://padlet.com/pauloberoi2/pik5qkwdxbawndes/wish/651939714 it took me 25 minutes to freeze the cold water and in the begging I just used common sense and I said to my self the cold water is gonna freeze first because it just has to get to the freezing point the hot water has to get to the cold point then the freezing point and the hot water was at the freezing point 5 minutes after cold]]> 2020-07-10 17:48:38 UTC https://padlet.com/pauloberoi2/pik5qkwdxbawndes/wish/651939714
