When a substance goes through a chemical change, it forms a new substance that has different physical and chemical properties. Often, chemical changes are caused by changes in temperature. Which of the following is a chemical change caused by a change in temperature? A. freezing a popsicle B. cooking an egg C. melting ice cream D. boiling water

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.

in chemistry, a solution’s concentration is how much of a dissolvable substance, known as a solute, is mixed with another substance, called the solvent. the standard formula is c = m/v, where c is the concentration, m is the mass of the solute dissolved, and v is the total volume

i would say b

explanation:

but i think i would need more information than that

girl imma just put my comment here because i need a couple point okurrttt
