Which three forces can affect an object without contact?

gravity, magnetic, electrostatic

can you attach a picture of the lettuce? : )

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.
