Question

8.p.8.1 states of matter notes name: q1 pd: ·explore the scientific theory of atoms (also known as atomic theory) by using models to explain the motion of particles in solids, liquids, and gases. step 1: study this content. you need to be able to demonstrate that you can do everything in the standard. options for studying: ·go to www.floridastudents.org. o click on science, m/j physical science and then 8.p.8.1. o click on the button for the tutorial (\your ice cream is moving\). complete the tutorial and take notes as you need. ·go to teams, unit 1 channel, and use resources i’ve posted there. take notes. you must submit these notes to get the 2nd part of the activity to earn recovery credit. define and illustrate (draw pictures) these terms: ·solid (particle model) ·liquid (particle model) ·gas (particle model) ·melting point ·freezing point ·condensation point ·boiling point ·kinetic theory of matter answer the following questions. also indicate what resource you used to find the information. 1) draw the heating/cooling graph of water and all three states of matter.

Explanation:

• Solid (particle model): Particles are closely packed in a fixed - regular pattern, with little movement. Illustration: Draw a grid - like structure with small circles (representing particles) in fixed positions.
• Liquid (particle model): Particles are close together but can move past one another. Illustration: Draw a group of circles that are touching but not in a rigid pattern, with some space for movement.
• Gas (particle model): Particles are far apart and move freely in all directions. Illustration: Draw circles that are widely spaced and moving randomly.
• Melting Point: The temperature at which a solid changes to a liquid. Illustration: Draw a thermometer with the melting - point temperature marked and an arrow showing the transition from solid to liquid.
• Freezing Point: The temperature at which a liquid changes to a solid. Illustration: Draw a thermometer with the freezing - point temperature marked and an arrow showing the transition from liquid to solid.
• Condensation Point: The temperature at which a gas changes to a liquid. Illustration: Draw a thermometer with the condensation - point temperature marked and an arrow showing the transition from gas to liquid.
• Boiling Point: The temperature at which a liquid changes to a gas. Illustration: Draw a thermometer with the boiling - point temperature marked and an arrow showing the transition from liquid to gas.
• Kinetic Theory of Matter: Matter is made up of particles that are in constant motion. The amount of motion depends on the state of matter and temperature. Illustration: Draw particles in different states (solid, liquid, gas) with arrows indicating their motion (slow in solid, moderate in liquid, fast in gas).

For drawing the heating/cooling graph of water: On the x - axis, mark time and on the y - axis, mark temperature. Show the flat sections at 0°C (melting/freezing) and 100°C (boiling/condensation) as water changes states while the temperature remains constant during the phase change. Indicate the solid (ice), liquid (water), and gas (steam) regions.

Answer:

• Solid (particle model): Particles closely packed in fixed pattern, little movement. Illustration: Grid - like with fixed circles.
• Liquid (particle model): Particles close, can move past each other. Illustration: Touching circles with movement space.
• Gas (particle model): Particles far apart, move freely. Illustration: Widely spaced, randomly moving circles.
• Melting Point: Temperature of solid - to - liquid change. Illustration: Thermometer with melting temp, solid - to - liquid arrow.
• Freezing Point: Temperature of liquid - to - solid change. Illustration: Thermometer with freezing temp, liquid - to - solid arrow.
• Condensation Point: Temperature of gas - to - liquid change. Illustration: Thermometer with condensation temp, gas - to - liquid arrow.
• Boiling Point: Temperature of liquid - to - gas change. Illustration: Thermometer with boiling temp, liquid - to - gas arrow.
• Kinetic Theory of Matter: Matter of moving particles, motion depends on state and temp. Illustration: Particles in states with motion arrows.
• Heating/cooling graph of water: X - axis time, Y - axis temp. Flat sections at 0°C and 100°C, indicate solid, liquid, gas regions.
