Heating Curve and Cooling Curve of Water - Enthalpy of Fusion & Vaporization

This chemistry video tutorial provides a basic introduction into the heating curve of water and the cooling curve of water. As heat is added to water, the temperature increases which increases the kinetic energy of the molecules. At the freezing point of ice, adding heat will not change the temperature but will increase the potential energy of the molecules as ice melts to liquid water. The enthalpy of fusion is the energy required to melt 1 mole of ice. The enthalpy of vaporization is the energy required to boil 1 mole of water into steam. The slope of the lines is inversely related to the specific heat capacity of the substance. The heating curve represents an endothermic process and the cooling curve is an exothermic process.

wow i’m really about to fail this chemistry test

[SarahDunham-qxtj]

You are amazing. Saving people’s GPA one video at a time.

[allaganator]

I wish I could pay you my tuition money instead of emptying my pockets at cal poly only to teach myself through your videos

[anosvoldigoad]

Thank you so much my teacher did not explain this at all and this really helped

[anissbenthami]

You deserve a big reward for these videos thank you thank you

[AwapeNembo]

Best teacher ever, you have helpd me with my daily lesson. I greatly appreciate your effort. ❤❤

[alondradelamora]

I’m watching this as I’m taking my finals for chem 😅

[The-hfzg]

Thank you so much, Is it possible to give an example of how much heat is evolved in converting steam to ice?

[georgesadler]

Professor Organic Chemistry Tutor, thank you for analyzing the Heating and Cooling Curve of Water graphically and analytically in AP/General Chemistry. For the Heating Curve, temperature, kinetic energy and potential energy increases in all stages of the curve. For the Cooling Curve, temperature, kinetic energy and potential energy decreases in all five stages of the curve. This is an error free video/lecture on YouTube TV with the Organic Chemistry Tutor.

[PhienixxStJames]

Explained it so much better than my chem book. It was like reading gibberish, until I watched this video.

[isabellasimpson]

my teacher just explained this and i wasn’t listening so i’m watching this now ;)

I have an argument with a friend: I’m sitting on a terrace. It’s 40C and sweating. I climb on my bicycle (or motorbike) and go for a ride. He claims that as the temp is at 40, hence above body 37C, my body will gradually warm up, i.e. there is no cooling effect, actually the contrary resulting in even greater discomfort. I claim there is a cooling effect. If I’m right, is there a point of temp where this effect reverses (sauna effect, when adding water in 80C room). Thank you to those knowledgeable out there.

[ummeytangimesha]

what are the factors influencing the slopes of each segment of the cooling curve and the length of horizontal segment

[darksavager]

I have reach the point that even if he's the one explaining it, I just can't understand this :<

[toshio]

Thanks! I grasped the main concept of it!!!!

[張洪鈞]

Thank you for this true video. If we could illustrate this problem of chemical bond and phase equilibrium value with other curve formula, like y=ax+b or y=ax^b, it's too hard.

[spongyleo]

Your not the only one who has that idea.😁😁😁

[mchii]

Damn he really starting speaking enchantment table on my ass 😭

[nanahafsatbaba-ahmed]

Please can you solve a question based on heat change from water to ice?

[madi]

"thank you The Organic Chemistry Tutor, " we all say in unison
