States of Matter; liquids

Liquids 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

Liquids MERCURY Mercury BROMINE Bromine reaction

Liquids 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.

Liquids Francium Cesium Gallium Rubidium

Liquids 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.

liquids 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.

liquids 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.

solutions 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

solutions Examples of solutions are koolaid- mixture of flavoring, sugar, & water soda- mixture of flavoring, sugar, carbonated water, & acid bubbles- mixture of glycerin, soap, & water windex- mixture of ammonia, water, fragrances, etc.
