My answers:
There are 3 states of matter. There are solid, liquid and gas.

# data[].attributes.body
1.  states of matter that exists in our world?
-Solid, gas and liquid

2. How do we change a state of matter? For example, solid to liquid? Liquid to gas?
-We can change a solid into a liquid or gas by changing the temperature when the temperature of a solid rises the particles that make up matter start detaching from one another and move more freely (solid to liquid =fusion) (liquid to gas = vaporization)

Solid, liquid and gas.

2.How do we change a state of matter? for example: Solid to liquid? Liquid to gas?

If heat is added to a substance, such as in melting, vaporization, and sublimation, the process is endothermic. In this instance, heat is increasing the speed of the molecules causing them move faster (examples: solid to liquid; liquid to gas; solid to gas).

(Solid to Liquid: fusion)
(Liquid to Gas: vaporisation)

2.How do we change a state of matter?For example,solid to liquid?Liquid to gas?
Solid to liquid (Fusion)
When the temperature of a solid rises the particles that make up matter start detaching from one another and move more freely.
Liquid to solid (Vaporization)
When a liquid is heated the bons from the particles that make up matter become more loose so particles move around freely.

Solid → Liquid: Melting or fusion
Liquid → Gas: Vaporization

We can change a solid into a liquid or gas by changing its temperature. This is known as changing its state. Water is a liquid at room temperature, but becomes a solid (called ice) if it is cooled down. The same water turns into a gas (called water vapor) if it is heated up.
