A pan at 20 degrees * C is put on a stove burner until it reaches equilibrium at 80 degrees * C . Soon after the pan is put on the stove, a cube of butter at O^ C is dropped into it. On the axes , plot temperature versus time for the bottom of the pan and also for the center of the cube of butter

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.

the answer is yes

it has kinetic energy

reason

an object has kinetic energy when you stop the force carrying it, the object will stay in motion.

hope this contact me for more questions if you'd like: )
