What I Learn About Matter...

Explanation
The three common states of matter are solid, liquid, and gas. In a solid state, particles are tightly packed and have a fixed shape and volume. In a liquid state, particles are close together but can move and flow, taking the shape of their container. In a gas state, particles are far apart and move freely, filling the entire space available to them. The given answer correctly identifies these three states of matter.

Explanation
Both liquids and gases have the ability to spread out and fill a space. In the case of liquids, the particles are closely packed but still able to move and flow, allowing them to take the shape of their container. Gases, on the other hand, have particles that are much more spread out and move freely, causing them to expand and fill any available space. Therefore, both liquids and gases have the property of spreading out to fill a space.

Explanation
Water can exist in all three states of matter: solid, liquid, and gas. In its solid state, water forms ice, while in its liquid state, it is the familiar liquid form we encounter every day. When heated, water evaporates and becomes a gas called water vapor. This ability to transition between states is due to the unique properties of water molecules and the changes in temperature and pressure. Therefore, the statement "Water can become all 3 states of matter" is true.

Explanation
When a solid changes into a liquid, it is called melting. This process occurs when heat energy is applied to the solid, causing its particles to gain enough energy to break free from their fixed positions and move more freely, forming a liquid state. The answer "melt" accurately describes this transformation.

Explanation
When a liquid changes into a solid, it is called freezing. Freezing occurs when the temperature of the liquid is lowered to its freezing point, causing the particles to slow down and arrange themselves into a solid structure. The process of freezing involves the removal of heat energy from the liquid, causing it to solidify and form a solid state.

Explanation
Matter is the correct answer because it refers to anything that takes up space and has mass. Matter can exist in various forms such as solid, liquid, or gas, and it includes all substances that we can observe and interact with in the physical world. This can range from everyday objects like furniture and water to more complex entities like cells and planets. In summary, matter encompasses all the material substances that make up our universe.

Explanation
This statement is false. When a liquid becomes solid, it undergoes a process called solidification or freezing. However, this solid can be converted back into a liquid through a process called melting. Melting occurs when heat is applied to the solid, causing its particles to gain enough energy to break free from their fixed positions and move more freely, resulting in a liquid state. Therefore, a solid can indeed become a liquid again.

Explanation
When water is heated, it undergoes a phase change and turns into a gas called water vapor. This process is known as evaporation. The heat energy causes the water molecules to gain enough kinetic energy to break the intermolecular bonds and escape into the air as gas. This is why we see steam rising from boiling water or feel the humidity in the air after a hot shower.
