Why would high pressure be an expected condition for the transformation of graphite to a more dense diamond.

"High pressur and low temperature favours the formation of ammonia in Haber's processs". Analyse the statement and illustrate the conditions using Le-Chatliers principle?

For a liquid-gas interface, the convex side has a high pressure than the concave side. Which is better, washing of cloth in cool soap water or warm soap water? Why?

On the basis of enthalpy of formation, graphite is more stable than diamond, yet diamond does not change into graphite for years. Explain why?

The following raphs are obtained for He at different conditions. The graph A is drawn at high temperature and low pressure and graph B is drawn at low temperature and high pressure. Which graph represents ideal behaviour?

Primary of a transformer has 20,000 turns and the secondary has 30,000 turns. 160V AC is applied at the primary ofthe transformer? lf the number of turns in the secondary transformer is greater than that in the primary then more voltage is induced in the secondary. Why?
