Study Definition and 1000 Threads

Hi there! A couple years ago, I failed my physics exam taken in upper secondary school (Norway), which has led me to having to retake the subject. I realize that I likely failed due to being lazy and tired of school. But a lot has changed since then, and I really do wish to learn physics. In...

I'm not sure if this is the correct thread, so please accept my apologies if I've posted in the wrong section. My question is for meteorologists and atmospheric scientists who did their undergraduate degree in different, but related fields, such as physics, chemistry, Earth science, etc. and...

The Clausius-Clapeyron formula is given by \frac{d P}{d T} = \frac{L}{T \Delta V} where P and T are the pressure and temperature at the boiling point, respectively, and L is the latent heat per mole at the boiling point, and \Delta V is the change in the volume per mole between the gas and...
