increases
Raising the temperature the density is lowered.
It's density will decrease.
they are compromised.
it becomes low
The density will decrease because the heated metal contracts and its particles slow down.
The density of air when it is heated decreases
It is reduced by haft
Thermal decomposition
Its density decreases.
In almost all cases, the matter expands. Density = mass / volume. When volume increases, the density decreases, because the mass is fixed.
In almost all cases, matter expands and becomes less dense when it is heated. Melting ice is an exception.
when motor oil is heated it viscotity rises and becomes thicker
