Will water molecules in hot water move faster or slower compared to molecules in cold water?

Will water molecules in water vapor (gas) move slower compared to those in liquid water?

What are some factors that can alter the speed of diffusion?

Solution

a) Water molecules in hot water move faster compared to molecules in cold water.

b) No:  In the gas phase—as water vapor—the H₂O molecules are farther apart. They move very fast and spread quickly compared to liquid water.

c) Answer: The factors that affect the rate of diffusion are
