Frage 29
Frage
Does temperature effect solubility? How so or how not?
Antworten
-
Temperature does not effect solubility.
-
Temperature 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.
-
Temperature 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.
-
Temperature 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.
Frage 30
Frage 31
Frage 32
Frage
Water can go between all three states of matter
Frage 33
Frage
How does temperature effect viscosity of a fluid? Does it? Explain-
Antworten
-
Temperature effects viscosity because the more energy, the more particles will move and the fluid will have a lower viscosity. Vice versa.
-
Temperature does not effect the viscosity of a fluid because the viscosity of a fluid depends on the types of particles it is made of.
-
Temperature 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.

-
For each substance, the amount of the particle never changes no matter how hot of cold the substance is.
-
For each substance, the amount of heat is evenly distributed to all of the particles so that the substance will have a consistent weight.
