Explanation:
- The image shows a triangle with three states of matter: solid (ice), liquid (water), and gas (cloud).
- The arrows show changes between these states.
- The red arrows are labeled "Endothermic," which means energy is absorbed (like when ice melts or water boils).
- The blue arrows are labeled "Exothermic," which means energy is released (like when water freezes or steam condenses).
- The cloud is at the top, which represents gas (water vapor).
- The ice is at the bottom left, which is solid.
- The glass of water is at the bottom right, which is liquid.
- The question asks about "The 4th state of Matter."
- The 4th state of matter is plasma.
- Plasma is formed when gas is heated to very high temperatures, causing electrons to break free from atoms.
- It is common in stars, lightning, and neon signs.
- So, the 4th state of matter is plasma.
