Pregunta 29

Pregunta
Does temperature effect solubility? How so or how not?
Respuesta
  • 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.

Pregunta 30

  • False

Pregunta 31

Pregunta

Pregunta 32

Pregunta

Respuesta
  • True
  • False

Pregunta 33

Pregunta
How does temperature effect viscosity of a fluid? Does it? Explain-
Respuesta
  • 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.

Pregunta 34

Pregunta
What is the definition of density?
Respuesta
  • The amount of matter in a given volume
  • The mass
  • The mass of the solid in liquid form

Pregunta 35

Pregunta
What is the formula to find density?
Respuesta
  • Divide the mass by the volume in order to find the density

  • False

Pregunta 38

Pregunta
According to the particle model:
Respuesta
  • For each substance, the number of particles in a given volume remains constant if the temperature is kept constant.
  • 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.

Pregunta 39

Pregunta
What happens to a substance as it heats?
Respuesta
  • The particles move faster
  • The particles spread apart
  • The volume increases

Pregunta
A substance has greater density in its solid state than in its liquid state
Respuesta

Pregunta 41

Pregunta
Why does hot air rise?
Respuesta

  • Hot air doesn't rise
  • Hot air rises because of air pollution

Pregunta 42

Pregunta

  • Because the water is warmer than the wood
  • Because the water is colder than the wood

Pregunta 43

Pregunta
The greater the friction or rubbing between particles in any fluid, the higher the viscosity. Therefore, fluids with a high viscosity do not flow as easily as fluids with a low viscosity.
