Explain, using the particle theory of matter, how diffusion takes place.

Explanation: When a pure substance's particle is moving from an area of high concentration to an area of lower concentration by occupying the spaces between the particles of another substance it is mixing or diffusing with. The particles of both the substances will mix or diffuse faster when the temperature is high.

tube or goog with be a great resource to with that question

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
