Davisson and Germer scattered electrons from a crystal of nickel.
The scattered electrons formed a strong diffraction pattern.
What significant conclusion was drawn from this experiment?
Ans- Electrons acted like waves
(i) A closed system consisting of 2 kg of a gas undergoes a process during which the relationship between pressure and specific volume is pv1.3 = c. The process begins with 1 p =1b
It is the property of changing readily from a solid or liquid to a vapour. It is the speed that a chemical compounds evaporates. Higher volatility indicates faster evaporation.
Does CPH mass increase? Answer; Never, mass of CPH is constant, as like its speed.
