How does a galvanic cell work? A. A voltage applied across two electrodes causes electrons to flow. B. A salt bridge connecting two electrodes generates electrons. O C. A redox reaction at two electrodes causes electrons to flow. D. Two electrolyte solutions react to cause electrons to flow.

C. A redox reaction at two electrodes causes electrons to flow

Explanation:

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.
