Chemistry

density, convection
1. water density=1g/cm3
2. anything will float in water if it is equal to or less dense
3. space
4. convection is the movement caused within a fluid with the tendency of hotter, therefore less dense material to rise and colder resulting in the fluid to sink, under the influence of gracity
6. when something is less dense is rises but when it is cooled it lowers. movement cause in a liquid caused by increasing heat
Diffusion
1. particle moving from high concentration to low concentration eventually reaching equalibrium
2. a way to speed up this process is to heat it
3. particles follow a convection current
4. particles are always moving due to kinetic energy or from a heat source
5. definition of kinetic energy= energy which a body possesses by virtue of being in motion
6. random motion and constantly colliding
7. current flow and the heat
States of matter
Other information
1. everything is made up of matter
2. matter exist is a solid, liquid or gaseous state.
3. the properties of matter can be arranged in terms of arrangement and energy
