It takes 6.86 kg of ethylene glycol (antifreeze; molar mass = 62.07 g/mol) to decrease the freezing point of 6.50 kg of water to -25 oF (-31.7 oC). How much sucrose (C12H22O11) would it take to decrease the freezing point of 6.50 kg of water to -25?

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.

what's the

d.) circle motion requires a force to give it a centripetal acceleration.
