Jamal’s teacher has asked the class to use this picture to explain how potential energy transforms to kinetic energy when an object begins to move.

D

Explanation:

I’ve had this question before. Since it’s stairs, the potential energy would decrease due to height decrease and it will be transformed to kinetic energy

a graduated cylinder.

explanation:

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.
