4/24/2023 0 Comments Simple states of matter worksheet![]() increases Thermal energy is the _ of potential and kinetic energy. decreases Potential energy _ as particles get farther apart. ![]() kinetic energy When the temperature of a substance _, particles move more slowly. gaseous Temperature is the measure of the average _ of all the particles in an object. faster Particles in the _ state have the most kinetic energy. Kinetic The _ particles move, the more kinetic energy they have. ![]() temperature at which a solid changes to a liquid melting point can result from adding or removing thermal energy change of state the change of state from a gas to a liquid condensation temperature at which matter changes from a liquid to a solid freezing point gas becomes a solid without first becoming a liquid deposition solid becomes a gas without first changing to a liquid sublimation _ energy is the energy an object has due to its motion. Condensation is when a gas changes directly to a solid. Sublimation is when a solid changes directly to a gas. Compare and contrast sublimation with deposition. Freezing is when a liquid changes to a solid. Melting is when a solid changes to a liquid. Temperature is just the total kinetic energy. decreases Compare thermal energy with temperature Thermal energy is the total of all of the kinetic energy and potential energy. ![]() As particles move closer together, potential energy _. vapor As particles move farther apart, potential energy _. volume, shape The gas state of a substance that is usually a solid or liquid at room temperature is called a _. Surface tension A gas has no definite _ and no definite _. cohesion _ involves the uneven forces acting on the particles on the surface of a liquid. viscosity The attraction between molecules that are alike is called _. volume, shape A measurement of a liquid's resistance to flow is called its _. faster A liquid has a definite _ but no definite _. amorphous The particle motion in a liquid state of a substance is _ than the particle motion in a substance's solid state. crystalline When particles in a solid are randomly arranged the solid is a(n) _ solid. When particles in a solid are arranged in a specific, repeating order, the solid is a(n) _ solid. When particles are close together, their attractive forces between them are _. Plasma When particles move more slowly, they move (closer together or farther apart) closer together. Examples: fluorescent lights, Sun/stars, lightning The three most common states of matter on Earth are: solids, liquids, gases Most matter in space is in this state. Examples: air, water vapor, carbon dioxide List 3 examples of plasma. They then bounce off and continue in a straight line. Particles move in a straight line until they collide with something. Particle force Explain the free motion of particles. What are 2 factors that determine the state of matter? Particle motion Evaporation can occur at any temperature at which matter is in the liquid state. Boiling is associated with high temperatures. While a liquid is boiling, does its temperature increase, decrease, or stay the same? Stays the same If the temperature of a gas is decreased, does its volume increase, decrease, or stay the same? Decrease When particles get hotter, do they move more quickly, more slowly, or at the same speed? More quickly As particle motion increases, what happens to kinetic energy? It increases As particle motion increases, what happens to temperature? It increases What are the 2 types of vaporization? Evaporation and boiling What is the difference between evaporation and boiling? Evaporation only occurs at the surface of a liquid. decreases What does the kinetic molecular theory explain? The kinetic molecular theor explains how particles behave within matter. If the pressure upon a gas increases, the volume _.
