Saliva is a liquid.
The general classes of colloids are sols (solid particles dispersed in a liquid), gels (cross-linked networks of solid particles dispersed in a liquid), and emulsions (liquid droplets dispersed in another liquid).
Germs are most commonly found in either liquid or solid form. They are typically carried in droplets, like saliva or mucus, or are present on surfaces. Gas-form germs are less common, as they would need to be suspended in the air.
Ice is a solid and when melted it turns into a liquid freeze it again and it is solid
the process of passing from a solid to a liquid is liquification but the passage from liquid to solid ist solidification
