Statement`: 8:8` co`-` ordination of `CsCl` at low temperature changes to `6:6` co`-`ordinationat `760K`.
Explanation`:` Temperature also infuences the strutures of solids.

Statement : 6:6 co- ordination at normal tempeature and pressure changes to 8:8 co - ordination at high pressure. Explanation : Pressure influences the structure of solids.

8:8 coordination of CsCl is found to change into 6:6 coordination :

8:8 coordination of CsCl is found to change into 6:6 coordination :

Why the coordination number of CsCl changes from 8 : 8 to 6 : 6 coordination?

Why the coordination number of CsCl changes from 8 : 8 to 6 : 6 coordination?

Statement - I. By increasing the temperature C.N. of CsCl changes from 8 : 8 to 6 : 6. Statement - II. Temperature also influences the C.N. of solid.

Element X crystallizes in a 12 co-ordination fcc lattice. On applying high temperature it changes to 8 coordination bcc lattice. Find the ratio of the density of the crystal lattice before and after applying high temperature?
