Thank you @Science Shorts for doing a kind gesture for all A-Level students. I had no hope for Physics but after discovering your channel, I watched every video which will come out of the exam. You gave me hope in doing Physics A-Level. I have just done the Physics A-Level P4 at Thursday and awaiting for the results. Thank you for your dedication and Keep up the Good Work. 😁😁

Why does isothermal compression happen at constant temperatures and why does the volume decrease and pressure increase? Also at a colder temperature I understand that the gas expands less but is that why the volume is lower?

Inside loop is net work done by gas. As in: total work done by it minus work done on it.

@wafflebuckets 4 жыл бұрын
Sorry for late reply. So basically U=q+w. Here w means work done ON the system. So the first law of thermodynamics would be: The internal energy of a system equals to the sum of the heat supplied and the work done on the system
