What causes matter to exist in three different states

NOT 100% SURE

Thermal Energy..?

When I think of three states of matter I think of water as an example:

• Adding extreme heat to the liquid form of water can turn it into gas.

• Adding heat to ice can turn it into the liquid form of water.

• Freezing the liquid form of water can turn it into ice.

I would say temperature (thermal energy) has an effect of the different states of matter.

organisms are more likely to be more preserved in mud than sand because mud is moist and wet, while sand is very dry.
