Question

In our lives, we rarely experience temperatures that are above 373 K (100°C) or below 273 K (0°C). Investigate how much diffusion rates differ between these two temperatures.

Answer 1

The rate of diffusion increases with higher temperatures as molecules have more energy and move faster. At 373 K, diffusion rates are significantly higher than at 273 K, because molecular motion is directly proportional to temperature.

Step-by-step explanation:

The student is asking about the effect of temperature on the rate of diffusion. Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration. According to the provided information, the rate of diffusion increases with higher temperatures because the molecules have more energy and move faster. Conversely, at lower temperatures, the molecules have less energy, which decreases their movement and the rate of diffusion.

At 373 K (100°C), particles have much more energy compared to when they are at 273 K (0°C). Therefore, the diffusion rate at 373 K is significantly higher than at 273 K. Since all molecular motion ceases at 0 K (absolute zero), we understand that temperature is directly proportional to molecular motion and diffusion rate.
