What does the law of conservation of energy state about energy in a closed system? Energy cannot be created or destroyed.
Energy can be created but not destroyed.
O Energy can be destroyed but not created.
O Energy can be either troyed or created.

Energy cannot be created or destroyed.

Explanation:

According to the law of conservation of energy, energy can neither be created nor it can be destroyed. Energy can only be transformed from one matter to another. The conservation of energy remains constant in an isolated system. The law is applicable in the system that does not exchange energy in the environment. Energy changes its form but remains constant.

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.
