You have two solutions of copper sulfate, one a deep blue and the other much paler. is the first or second likely to be more concentrated? is the first or

Explanation:

particles move rapidly in all directions but collide with each other more frequently than in gases due to shorter distances between particles. With an increase in temperature, the particles move faster as they gain kinetic energy, resulting in increased collision rates and an increased rate of diffusion
