Topic 3 Thermal Physics

astra:"These videos are lessons/tutorials that are intended for IB Physics students or teachers. Most lessons include sample IB questions that students are asked to solve before taking up the answer. My hope is that the videos will replicate for many, the experience of this student: I would just like to say a massive thank you to you for uploading your videos. I started the IB in 2013 and decided to try HL Physics as it seemed interesting. It turned out to be very far from my forté and I was consistently getting 3s and 4s in tests and mock exams. So a few months before the exam period of this year, I began to panic...Then I discovered your channel. For four weeks prior to paper one, I virtually worshipped your videos, and worked along to them in my 'Big Book of Revision.' Last week, I received my results. Incredibly and almost unbelievably, I obtained a 6 in HL Physics. Not only that, but I was 3 marks off a 7."
