29Does temperature effect solubility? How so or how not?
- ATemperature does not effect solubility.
- BTemperature effects solubility by making the particles closer together so that other particles cannot slide in between them. No matter what temperature you heat or cool the solvent to, this will always be the same.
- CTemperature does effect solubility. When heated, particles spread out and when cooled particles get closer together, either allowing particles to go in between each other or not. The hotter the solvent, the higher the saturation point, vice versa.
- DTemperature does not effect solubility because the particles do not react to different temperatures. They kind of just do what they want as the travel around and between each other.

- BFalso
32Water can go between all three states of matter

33How does temperature effect viscosity of a fluid? Does it? Explain-
- ATemperature effects viscosity because the more energy, the more particles will move and the fluid will have a lower viscosity. Vice versa.
- BTemperature does not effect the viscosity of a fluid because the viscosity of a fluid depends on the types of particles it is made of.
- CTemperature effects the viscosity of a fluid by making the fluid almost a solid if it has any viscosity at all, if it has no viscosity then it will be like water.

38According to the particle model:
- AFor each substance, the number of particles in a given volume remains constant if the temperature is kept constant.
- BFor each substance, the amount of the particle never changes no matter how hot of cold the substance is.
- CFor each substance, the amount of heat is evenly distributed to all of the particles so that the substance will have a consistent weight.
39What happens to a substance as it heats?

40A substance has greater density in its solid state than in its liquid state
- AVerdadero
- BFalso
41Why does hot air rise?
- ABecause hot air has more space between the particles so it becomes lighter, vice versa.
- BHot air doesn't rise
- CHot air rises because of air pollution
42Why does wood float on water?
- ABecause the water has a greater density than the wood
- BBecause the wood has a greater density than the water
- CBecause the water is warmer than the wood
- DBecause the water is colder than the wood

48Define the characteristics of a homogenous solution:
