Thanks . Not complaining, and was a great explanation. Most explanations of latent heat are explained this way but it really leaves a lot out of the way it’s taken advantage of. Cooling towers and evaporative coolers make use of the latent heat of evaporation well below the boiling point of water. Tying this to how cooling happens with evaporation is hard, with me anyway , with the general explanations of latent heat like this video. Such as hot air blown across wet pad in an evaporative cooler. As evaporation occurs the dry bulb temp decreases as the energy from the air used to evaporate the water, there is now less heat in the air that passed . The vapor from evaporation isn’t increasing in temperature as it absorbed the energy from the warm air, but the humidity is increasing.
5:12 "You can see here it doesn't require quite a bit very much heat energy to rise at to raise that temperature from 32 to 212 degrees." First, the viewers' ability to comprehend is taken as a given, which is frustrating if one is not tracking. Why might one not be tracking? Well, for one thing the saying "it doesn't require quite a bit very much" and "to rise at to raise that" are odd and so a bit difficult to follow. Secondly, the imprecision of the telestration is distracting: is the energy at 212 degrees 340 Btu? Or is the energy slightly less, say 330 Btu, as the speaker telestrates? And furthermore, why does the speaker consider that the energy required to change the state from ice to liquid is "not very much"? Well, certainly relative to the energy required to change the state of water to gas it is not very much, but isn't this an apples to oranges comparison? But it is, however, a larger amount of energy than is required to change ice to water. So what does "not very much" mean? And why is it relevant to the discussion? I've only pointed out one sentence is a seven minute presentation.

Thank you Mr. Walker for making this understandable.
Thanks, I’m just starting classes. Wish me luck!
Finally I understand. Thank you!
Thank you for helping to clear that up for me
Thank you for making this video. I finally understand the difference :)
THANK YOU!
can you tell us sensible heat formula how to calculate sir
Thank you
Well done..thanks !!
plasma is a form of matter as well
This is an HVAC training presentation, not a nuclear fusion discussion.
Very nice
Eureka!!
thank you:)

oh god am i lost
trying to calculate how many btus are in the latent heat stage
Sadly 2nd disliker
