Summary: The transition Sn(s, gray) ⇌ Sn(s, white) is in equilibrium at 18°C and 1 atm pressure. If ΔS = 8.811K mol for the transition at 18°C and if the densities are 5.75 g/cm3 for gray tin and 7.28 g/cm3 for white tin, calculate the transition temperature under 100 atm pressure
What does it tell you about a substance? A hight melting and boiling point means that the molecules hold together strongly, as in tungsten. A low melting point, as in hydrogen, means they're kinda loose. But what does the distance between them tell you?
Something something entropy yadda yadda...
I found this video on Youtube of this guy boiling water by reducing the pressure:
I'm not sure how the gauge he's looking at works but I think this is the vacuum instrument he's using: https://us.vwr.com/store/catalog/product.jsp?product_id=4789427

what is the definition of phase lag and phase difference in waves and how are these 2 related?please explain in simple words and with real life examples.
Please explain phase,phase lag and phase difference from scratch.
I need help in determining the type and stability of the fixed points in this system.
