Heat causes melting and evaporation; cooling causes condensation and freezing. If you'd like to learn more, I can explain: The fourth state (Plasma) Specific melting and boiling points How pressure affects these states
Katı was the oldest and the most disciplined. He loved order. He and his particles would stand shoulder-to-shoulder, holding hands so tightly that they couldn’t move from their spots. "We have a fixed shape and volume," Katı would say proudly. No matter what container he sat in, he stayed exactly the same, strong and unyielding. Kimya Maddenin Halleri
Particles move rapidly and are far apart. Fills all available space. Particles move rapidly and are far apart
Sıvı was the middle child and much more relaxed. She liked to go with the flow. While her particles still stayed close enough to touch, they didn't hold hands tightly like Katı’s. Instead, they slid and danced past one another. "I don't care about having my own shape," Sıvı laughed. "I’ll just take the shape of whatever cup or bowl I’m in, though I always keep my volume consistent." Takes the shape of its container.
Particles are tightly packed, vibrating in place. Has a definite shape and volume.
Gaz was the youngest and the wildest of all. He couldn't stand being still or staying close to anyone. His particles zoomed around at high speeds, bouncing off the walls and flying far apart. "I want to fill everything!" Gaz shouted. He had no fixed shape or volume; he would expand to fill an entire room or shrink to fit into a tiny balloon if you squeezed him.
Particles are close but can slide past each other. Takes the shape of its container.
