Diffusion D. Osmosis This experiment is an example of Temperature can affect rate of diffusion. Aniline Blue diffuses at a slower rate because of its low molecular weightExplanation / Answer
Answer- True
Explanation-
Heavier molecules tend to move slowly whereas molecules with low molecular mass tend to move at a faster rate. So, dye with low molecular weight will move at a faster rate.
Answer- False
Explanation-
Rate of diffusion is directly proportional to temperature. This means that the higher the temperature, the faster is the diffusion of the molecules. Here, since the temperature is low the molecules will not diffuse at a faster rate.
Answer- Diffusion
Explanation-
Diffusion is regarded as the movement of molecules from a region if higher concentration to a region of lower concentration as a result of random motion if the molecules.
Answer- True
Explanation-
The Rate of Diffusion depends directly on the temperature. This means that at higher temperature the rate of diffusion will tend to be at a higher rate.
Answer- False
Explanation-
Aniline blue diffuses at a slower rate because its molecular weight is very high. Molecules with low molecular weight tend to diffuse at a faster rate rather than those with high molecular weight.
