Explain Boyle's law in terms of kinetic theory

Answer»

According to me,
The kinetic molecular theory can be used to explain each of the experimentally determined gas laws. The pressure of a gas results from COLLISIONS between the gas PARTICLES and the walls of the CONTAINER. Each time a gas particle hits the WALL, it exerts a FORCE on the wall.

Ionization potential of He+....

Answer»

Hi , there !!!

He+


IONIZATION potential => K × Z² / n²

K = -13.6ev


ATOMIC NUMBER of Helium = 2

number of orbit = 1


K × Z² / n²

=> 13.6 × ( 2)² / 1²

13.6× 4

=> 54.4ev
