TRANSCRIPT
A liquid is defined as matter that has a definite volume BUT has no definite shape.
Molecules are always moving… fluidity. There are two elements that are liquids
at room temperature (25°C/ 77°F); MERCURY & BROMINE
MERCURYMercury
BROMINEBromine reaction
But, as you heat things up… four more elements become liquid.
For temperatures up to 40°C (104°F) Francium, Cesium, Gallium, & Rubidium will become liquids.
Notice that Bromine is the ONLY nonmetal that is in the liquid state.
Francium
Cesium
Gallium
Rubidium
There are other types of liquids too. (that are not elements)
water (H2O)
rubbing alcohol (C3H7OH)
These are pure liquids that have their own individual properties.
BUT, most things are mixed. When you put things together, that don’t mix, they call that a heterogeneous mixture.
These are chunky mixtures and may separate out over time.
One example is muddy water.
BUT, when you mix things together, and they stay together, it is called a SOLUTION.
Solutions are homogeneous mixtures which are smooth, uniform throughout.
Once mixed, the components will stay mixed. One example is salt water.
There are three types of solutions
unsaturated solution – more stuff can be still be mixed in the solution
saturated solution – the perfect amount of stuff is in the solution
supersaturated solution – extra stuff was mixed in the solution super demo
Examples of solutions arekoolaid- mixture of flavoring, sugar, & watersoda- mixture of flavoring, sugar, carbonated water, & acidbubbles- mixture of glycerin, soap, & waterwindex- mixture of ammonia, water, fragrances, etc.
1. Decide which element you would like to adopt.
2. Organize your binder
