Pressure and Density - GCSE Physics Revision - SCIENCE WITH HAZEL

[@Khadijahx238]

I received an A because of this video Thank you so much !

[@nimo2714]

I’m doing paper 2 tomorrow paper 1 density hasn’t come up so I’m going over this guessing it will on paper 2 wish me luck 🤗

[@sithukisawanmee]

Thank you so much ma'am ❤

[@ceciliaadumensah]

I am soo confused at 12:33 where did you get the equation for b from?

[@shimantorahman8324]

pressure = h(height) x p(density) x g(gravity)

@@shimantorahman8324 oh thank you!

[@thaliaissa3009]

can sm1 explain why its wrong to say that once the gas or liquid is heated the ' particles expand' and what we should say instead

[@SciencewithHazel]

Because the particles themselves do not expand. The gas or liquid expands because the distances between the particles become greater due to the particles having more kinetic energy

[@thaliaissa3009]

Is it valid to say that the volume in which the gas or liquid occupies will increases for the same mass once the fluid is heated ?

[@SciencewithHazel]

Yes, it is

[@maheerawaseem6784]

can you plz make a video on common mistake students make in their boards and your advice, that'll be great

[@mrnobody6942]

Hey hazel! I was wondering if this video is applicable for Igcse physics edexcel?

[@SciencewithHazel]

Yes it is

0:01 horrible caption but great video

[@izzydev05]

I would like the video but it's at 69 likes. (For those of you who don't know, 69 is the funny number)

[@antwidavid389]

Brooooooooooo I was just about to like it when I saw the video is now at 96 likes what a coincidence😂
