You're videos really are excellent. I'm using them almost exclusively for my classes while we're home learning. I plan to keep using them once normality resumes. I hope you're seeing an uptake in views and subscribers!
You all prolly dont care but does anyone know a trick to log back into an Instagram account..? I was stupid forgot the account password. I love any assistance you can offer me.
some misconceptions I think: temperature is proportional to THERMAL energy, not INTERNAL energy (which includes the potential energy stores of the particles too)
@@iya4631 I’d love to be a cardiologist lol- taking maths, bio and chem at a level rn it’s going well I think, wbu? What do u wanna be?? Also tysm for the congrats 😭
How does this person explain the concept in five minutes when my physics teacher couldn't do it in 100 minutes?!?!?!?!?!????? This is incredible hahaha
00:05 Internal energy relates to temperature using specific heat capacity 00:39 Heating a substance increases its internal energy. 01:13 Internal energy determines temperature 01:48 Specific heat capacity measures energy needed for temperature change 02:22 Internal energy equals mass times specific heat capacity times change in temperature 02:56 Calculating change in temperature using specific heat capacity of water 03:32 Converting energy units and calculating final temperature change. 04:04 Energy loss to surroundings affects temperature change
Some Pople go for the complex looking videos because they think they will become super scientists when what they actually need is a 5 mins video which explains all they need while saving time.
THIS GUY HAS PUT ME IN SO MUCH CONFUSSION!!! In 1:16 He says that temperature is a "measure of the average internal energy of a substance" and this is WRONG. Temperature is apparently the measure of only the average kinetic energy!!!
Your videos Are really helpful But could you please add more practice Questions and it would be better if its from a past exam paper . I would really appreciate it
@@AayushChitnis it obviously did Mae sense bc everyone else is learning from it ur just a pessimist who thinks he's cool bc his opinion differs to everyone else's even if its wrong
