level questions: Particle Theory and States of Matter

QuestionAnswer
What are the 3 States of Matter?-Solid -Liquid -Gas
What is different in the States of Matters?-Simply only the Energy Arrangement
What are Physical Changes?-Simply just changing the State that Particles were in -Example, Melting
Explain the Arrangement and Forces in a Solid-Has Strong Forces of Attraction, that hold the Particles very Close together in a Fixed Regular Arrangement -Particles have a Low Amount of Energy in terms of Kinetic Energy, so they can only Vibrate if most
Explain the Arrangement and Forces in a Liquid-Forces of Attraction between the Particles are Weaker, so the Particles can Move and Slid on top of each other, whilst being still Close -They have More Energy in terms of Kinetic Energy, so they can Move in Random Directions, at Low Speeds
Explain the Arrangement and Forces in a Gas-Virtually no Force of Attraction between the Particles, so that means the Particles can Fly Around -They have most amount of Energy, in terms of Kinetic Energy. They can travel in High Speeds in Different Directions
What exactly is the Thermal Energy Store?-Its literally the Kinetic Energy Stores. It holds the Thermal Energy
What happens when you heat a Liquid, in terms of Energy Stores-Energy is given to the Kinetic Energy Stores, allowing them to move even Faster. -When enough Particles can overcome the Attraction, big Bubbles of Gas can Form [Boiling]
What does working with a Closed System mean?-Simply means that no Particles can Escape, and no new Particles can Enter
Is the Mass affected by changing State?-No -This is because the Mass of a Substance is the Mass of the Particles, and the Particles aren't changing, just being Rearranged
Does Density change with the Changes of States?-Yes -Since the Volume also can change because -A Solid has the Particles closer than a Liquid -A Liquid has the Particles closer than a Gas -Water and Ice, are the 2 Exceptions
