During springtime in Alaska, frozen rivers thaw and boats can navigate te rivers again, What physical changes occur to the ice molecules when? Explain te process in Which water in te river changes to water vapor

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.

i would say b

explanation:

but i think i would need more information than that

the answer is option a.
