Density m/v
Which state(s) of matter take on gases and liquid
the shape of their container?
Do molecules ever stop molecules are never still, they always have energy, no matter the
moving? phase
- solid form is less dense than its liquid form
- all three of its physical states can be found at naturally
How water is different than
occurring temperatures on Earth
other molecules:
- it is a very "sticky" molecule, giving rise to many characteristics
vital to life of Earth
, Compounds made up of 2 elements combined
How do we distinguish between - think about what happens at the macroscopic and
a physical and a chemical submicroscopic levels
change?
- helium: gas expands, balloon can't contain, will pop because of
Examples of physical change positive pressure
- heterogenous mixture
- combustion (hydrogen gas, reacts with the oxygen outside of
the balloon.
Examples of chemical change
- explosions (hydrogen and oxygen, controlled combustion
reaction)
