1. Define Matter and States of MatterMatter is anything that has mass and takes up space.States of Matter are the physical forms in which matter exists. The main states are:SolidLiquidGas(Also: Plasma and Bose-Einstein Condensate, in advanced levels)2. What is the difference between a liquid and a gas?Liquid has a definite volume but no definite shape. It takes the shape of its container.Gas has neither a definite shape nor a definite volume. It expands to fill the container.3. What is the process called when matter changes from a solid to a liquid?The process is called Melting.4. What is the difference between a solid and plasma?Solid has a fixed shape and volume, with particles packed tightly together.Plasma is a high-energy state of matter where gas particles become ionized (electrically charged) and move freely. It's found in stars and lightning.5. What are the physical properties of matter?Physical properties of matter include:MassVolumeDensityColorOdorBoiling pointMelting pointState (solid, liquid, gas)6. Describe the arrangement of particles in a gasIn a gas, particles are:Far apartMove freely and quickly in all directionsHave no fixed positionFill the entire volume of the container
