write down the expriment which shows that particles have very tiny size
Answers
Answer:
the answer is
Explanation:
Students will develop a model to describe that matter is made up of tiny particles, too small to be seen. Students will use the model to describe the differences in attraction among the particles of a solid, liquid, and gas. Finally, students will use their models of solids, liquids, and gases to explain their observations in the lesson.
Key Concepts
Matter on Earth is in the form of solid, liquid, or gas.
Solids, liquids, and gases are made of tiny particles called atoms and molecules.
In a solid, the particles are very attracted to each other. They are close together and vibrate in position but don’t move past one another.
In a liquid, the particles are attracted to each other but not as much as they are in a solid. The particles of a liquid are close together, always moving, and can slide past one another.
In a gas, the particles have very little attraction to each other. They are very far apart compared to the particles in a solid or liquid, and are constantly moving. The particles don’t interact with one another but just hit and bounce off of each other when they collide.
