Which of the following leads to a higher rate of diffusion?
miv72 [106K]
<h3><u>Answer;</u></h3>

Higher velocity of particles

<h3><u>Explanation;</u></h3>

The diffusion rate is determined by a variety of factors which includes;

  • Temperature such that the higher the temperature, the more kinetic energy the particles will have, so they will move and mix more quickly and the diffusion rate will be high.
  • Concentration gradient such that the greater the difference in concentration, the quicker the rate of diffusion.
  • Higher velocity of particles increases the diffusion rate as this means more kinetic energy by the particles and hence the particles will mix and move faster, thus higher diffusion rate.

I would say that it's C. Seasonal temperatures have dipped over time, but I could easily be wrong, since it's my opinion. A weather condition is defined as the atmospheric conditions that 'comprise the state of the atmosphere in terms of temperature and wind and clouds and precipitation. But I believe it could just as easily be B. 150mm of rainfall is a normal average in the city.
