Curie's Law

Correct the following statement:

Curie Law states that $\mathrm{X}=\frac{\mathrm{C}}{{\mathrm{T}}^2}$, where $X,C,T$  is magnetic susceptibility, Curie temperature, temperature.

Correct the statement:

Curie-Weiss law is applicable for diamagnetic materials.

The magnetic susceptibility of a paramagnetic material changes inversely as the absolute temperature.

Iron is a ferromagnetic substance. Can it be converted to a paramagnetic substance? If so, under what conditions and why? Can we have a ferromagnetic substance in a liquid form?
