The substance 'X' normally exist in a physical state which ca flow easily but does not fill its vessel completely. It also turns dry copper sulphate to blue. When substance'X. is cooled excessively, It changes into a substance'y' which has a fixed shape and fixed volume. If, the substance 'x' is heated strongly., it changes into substance'z' which has neither a fixed shape not a fixed volume. At which temprerature 'x' gets converted into'z' ?
