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