| Question | Answer |
| what are three states of matter | solid,liquid'and gas |
| describe how solid particles are arranged | compacted and vibrating in fixed postions |
| Explain how liquids are different from solids | liquid - is a state of matter where the particles 1. have more kinetic energy than solids 2. are not as tightly packed as a solid 3. are able to flow taking the shape from the bottom of a container 4. are compressible (hydraulic brakes) |
| Gases can be described as a state of matter that .......... | 1. has the most kinetic energy 2. has very loosely packed particles 3. can flow, spreading outward to fill any shape or container 4. is more compressible than liquids (stay 17 meters behind a truck with air brakes) |
| Then explain what is matter? | 1. matter is anything that occupies space and has mass 2. particles of matter are in constant random motion forming 3 possible states |
| Describe an experiment diffusion as it is used to prove the particle nature of matter. | 1. Diffusion of tang crystals in water from a region of high concentration to a region of low concentration until evenly distributed throughout |
| Discuss two other ways of PROVING THE PARTICLE NATURE OF MATTER | 2. OSMOSIS as water moves from a region of high concentration in the cell's of fruit to a region of low concentration across the cell membranes to the outside until equilibrium. 3. BROWNIAN Motion where particles of pollen in a dish of STILL water, can be seen zipping about randomly. |
| Explain the process shown in the diagram | Diffusion is shown as red solute spread out evenly from a region of high concentration in the top left of the beaker to a region of low concentration spread throughout the solution. |
| Explain the process shown in the diagram | BROWNIAN Motion where the yellow particles shown is bombarded by the smaller less conspicuous blue particles causing the more visible yellow particle to be seen zipping about randomly. |
| Explain the process shown in the diagram | OSMOSIS as the water (in red) move from a region of high concentration across a semi permeable membrane to a region of low concentration until equilibrium. This can be seen evident in the rise of the water level on the right |
