The element mercury has several unique properties, including that it expands when heat is applied, making it useful for making thermometers.
Water expands when it freezes and becomes ice.
That is normal. The fluid expands when heated.That is normal. The fluid expands when heated.
Matter generally expands when heated and contracts when cooled. This is due to the changes in the kinetic energy of the particles within the matter. The expansion or contraction allows matter to adjust its volume to the space available.
When any state of matter is heated it expands.
if matter expands to fill the volume of its container its a suspension.
The huge desert that expands from China to Mongolia is the Gobi desert.
Titanium has a relatively low thermal expansion coefficient compared to other metals, meaning it expands less when heated. This property makes it useful in applications where dimensional stability is important.
Water
Air expands the most.
that water expands when it gets cooler , other forms of matter expands when it gets hotter.
It is not that 20 per cent of the water expands - all of the water expands.
