Asolution of ammonia and water contains 3.80×1025 water molecules and 8.60×1024 ammonia molecules. how many total hydrogen atoms are in this solution?

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.

the answers would be

the first one and the second one
