Sir ,according to Charles law ;at constant volume ,as the temperature increases pressure also increases then how could C.N decrease with increase in temperature ?
Hema chandhu that law was for gases and here we are talking about solids . As we increase the temperature the atoms start moving from their places and then they get apart which causes a decrease in the cordination no. Of atoms (solids )
The law was for gasses. Also The volume is not constant as volume decreases when pressure is increased. This is because the temperature is kept constant not the volume when p is increased. PV = C
