What effect will the number of particles and temperature have on the rate of diffusion of gas molecules? a. the rate of diffusion decreases with the increase in number of particles and temperature. b. the rate of diffusion increases with the increase in number of particles and temperature. c. the rate of diffusion increases with the increase in number of particles and decrease in temperature. d. the rate of diffusion decreases if the number of particles and temperature are kept constant. e. the rate of diffusion increases if the number of particles and temperature are kept constant.

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.

in cartography, a contour line (often just called a "contour") joins points of equal elevation (height) above a given level, such as mean sea level. a contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes.
