Which statement describes the law of conservation of energy? O All systems will exchange matter and energy with their surroundings.
O All systems can exchange energy, but not matter, with their surroundings.
O Energy cannot be created nor destroyed, but it changes from one form to another.
O Energy is destroyed in most chemical reactions when new products are formed.

Explanation:

Energy cannot be created nor destroyed, but it changes from one form to another.

in physics and chemistry, the law of conservation of energy states that the total energy of an isolated system remains constant; it is said to be conserved over time. This law means that energy can neither be created nor destroyed; rather, it can only be transformed or transferred from one form to another.

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.
