Q: List as many objects or substances you can think of and put them in the following 3 categories: SOLID, LIQUID, and GAS. |
A: SOLIDS: Ice, Lab Tables, Lab Chairs, Pencils, Laptops, Calculator LIQUIDS: Water, Food Coloring, Milk, Soda, Salad Dressing GASES: Water Vapor, Carbon Dioxide, Carbon Monoxide, Methane, Oxygen, Nitrogen |
|
|
Q: What exactly is matter? Also, list the 3 states of matter. |
A: Matter is anything that has weight and takes up space. The three states of matter are solid, liquid, and gas. |
|
|
Q: Describe the way particles are arranged in a solid, liquid, or gas. |
A: Matter is anything that takes up space and has weightTiny particles inside matter are atoms and moleculesA solid has rigid structure and barely movingA liquid has a free-moving structure, but stay in a containerA gas has completely free-moving particles everywhere. |
|
|
Q: What can you tell me about the motions of molecules in cold water? |
A: Molecules in cold water are closer togetherThey are still moving, but much slowerParticle are NOT rigid and still |
|
|
Q: What can you tell me about the motions of molecules in hot water? |
A: Liquid molecules generally move faster than solids, but slower than gasesMolecules in hot water are farther apartHOT LIQUIDS molecules move quick/fast, and also spread apart. The particles are not rigid and stillNot as fast or spread out as a gas |

|
Q: Why is it so easy to put a dent in a ping pong ball or a tennis ball, but not so easy to put a dent in a soda can? |
A: Gas molecules move fast and are far apart.Inside of a tennis or ping pong ball, there is only a gas. Inside of a soda can, there is no room to move freely-no empty space.It is easier to make a dent in the tennis ball or ping pong ball because there is only gas, but it is harder to put a dent in soda can because they are a liquid(Coca-Cola) and a gas (carbon dioxide) |

|
Q: What do you think is happening in the giant barrel at the moment of the crush? |
A: Inside the barrel, water is being heated. Molecules are fast-moving and are very spread out. Once the barrel is inside the pool of ice and cold water is being sprayed, water molecules are slowing down and getting closer together. Change in temperature is so fast the barrel caves in on itself. |
|
|
Q: How do you think ice cubes change from a solid to a liquid? Hypothesize what you think is happening in a few sentences. |
A: Heat and energy help a solid ice cube change for a solid to liquid. Ice cube is absorbing all the heat energy from the classroom. |
|
|
Q: Describe what happens when a PHASE CHANGE occurs. 30 minutes. I will study in my room with my sister. She already took the test, so she knows the right answer. She can also help me, if I seem to struggle with something. Later before I go to bed I will study on quizziz. |
A: A PHASE CHANGE is a change in any of the 3 states of matter to another state. Phase changes in matter occur when there is an increase or decrease in ENERGY, HEAT, or PRESSURE. Examples: Melting, Freezing, Condensation, Vaporization |
|
|
Q:Name the two types of vaporization. |
A:Vaporization occurs when we change from a liquid to a gas.Types:Evaporation-Occurs only on the surface of the liquid.Boiling- Occurs on the surface and below the surface of the liquid. |
|
|
Q:n View the two links attached to your Schoology Update and describe what ”Sublimation” is in a few sentences. A: Sublimation is a PHASE CHANGE. A solid changing directly to a gas and skipping the liquid phase.Dry ice is an example of the phase change sublimation. |
