An ideal gas cannot be liquified because forces between the molecules are negligible.

On the basis of magnetic properties, substances are classified into three groups namely diamagnetic, paramagnetic and ferromagnetic.

As solids diffuse and reorder very slowly under ambient conditions, the net, directionally dependent (anisotropic) magnetic moment can persist. Conversely, liquids and gases freely tumble and reorder: water rearranges every few pico seconds (10^12 times per second).

Hence liquids and gases can never show ferromagnetic properties.

The soil is formed by breaking down of large rock surfaces into pieces due to water, wind and all atmospheric changes by mixing with plants and animal decays. This process is called as weathering.

Hard real-time systems required to complete a critical task within a guaranteed amount of time.
Soft real-time computing requires that critical processes receive priority over less fortunate ones.
