Thank you so much for the video! I was so stressed about my IB physics class! Your video and playlists literally saved me as a student :D So thank you!!
I must say, Mr. Masley, you consistently surpass the previous one with each video you do. I'm pre-studying IB physics so I can get a jump on the DP. Your videos are probably the best resource out here on the internet for IB Physics. I'm going to be sharing your channel on Reddit for anyone who wants to revise content or practice.
4:24 you said it was required a total 10J to turn that liquid to a SOLID, but in 4:37, after you had added 10J, you said the bond were then disappearing, the matter turned into GAS. I couldn't make neither my head nor tail at this part. Can you explain it clearly to me?
First of all, I wanted to say thank you for making IB Physics so much easier for me to understand through these videos! I wanted to ask a question: how do the particles "know" when they have become a liquid and the energy stops affecting their bonds? Why doesn't the energy keep affecting its bonds even though it has changed state e.g. going from solid to gas instead of stopping at liquid?
You mention that the boiling point is the temperature at which the phase of the substance changes from liquid to gas or vice versa, but if the substance were to go from gas to liquid it would need to condense, which happens at the condensation point. Now looking online, a lot of sources say that for most things this temperature is the same for both, but in what cases can these two temperatures change and why?
At 10:11, why does the specific heat capacity fluctuate? Why does it increase from solid to liquid and then decrease to lower than the solid for the gas?
Hey andy, today me and my teacher got in a scuffle about temperature and pressure. A question on my quiz read "for a liquid to become a vapor it MUST absorb heat" I answered false and got the question wrong, my reasoning was that you can get the same effect by removing the pressure from the environment. He insisted that it must absorb heat regardless because the temperature through the phase change is not constant, i argued its because the pressure. help me out with this, thanks.
Im not sure but doesn’t temperature stay constant during a phase change and only the potential energy change, in this case it should increase as the distance between particles increase going from liquid to gas. Furthermore, pressure is directly proportional to temperature meaning if you remove pressure from its environment, the temperature should also drop, therefore the liquid would technically freeze up becoming a solid instead of a gas.
can't stress enough how all of these videos are amazing for revision

Also, do you know if you're going to be doing videos on HL topics aswell?
I have been so confused on the potential energy part of this model. Thank you!!
What a great detailed explanation. Loved your video. Thank you so much!

Good catch, I misspoke and should have said gas, not solid

In other words, what exactly causes materials to have specific boiling and melting points?
Thank you much this video because this may report in school tomorrow.
Brilliant more lectures please

This video was really helpful as it really cleared all my doubts, thanks a lot
But sir can you pls explain what is latent heat?
I think you videos are underrated, your way of explanation is brilliant, please do some more videos on mechanical concepts
My year's been much much busier than previous years so I apologize for not making more, I'll hopefully have time soon
do you offer this ppt for sale?
