Transcript of water water in the water

Rainbows form when water droplets are a light mist and the sun passes through the drops, which makes a prism of rainbow light that comes in red, orange, yellow, green, blue, indigo, and violet. Sometimes, even pink is visible. water storing heat The water cycle (a.k.a hydrological cycle) circulates water around the world. The water cycle works like this: water goes up to the sky and creates a cloud which is called evaporation. Then when it's full it goes down as precipitation. When it's rain, it blows wind the window and it makes the liquidy air to the window which is called condensation. Rain can also water plants which is called transpiration. The extra water goes back in the river, pond, or ocean, and the cycle starts again. (Liquid) to flow with no tendency to disperse and high impressibility
(solid) forces and compresses to its surroundings shape
(gas) matter distinguished from the solid and liquid by low density and viscosity (ionic solid) these substances have a melting point and contain ionic bonds
(coralent solid) this substance appear as a single giant molecuel made of numbers of conralent bonds
(moleculer solid) are described as repeating units made of molecules (metallic solid) are reapiting units made of metal atoms DEnsity
is the amount of mass in a unit of volume aerogels lighest
solid the density
of 1.9 mg!!!! W
R Two men walk into a bar. The first man says, "I'll have some H2O." The second man says, "That sounds good, I'll have some H2O too."

THE SECOND MAN DIED. water is distributed on earth as freshwater for humans and the salt water goes in the ocean. CAPACITY OF WATER It take Two men walk into a bar. The first man says, "I'll have some H2O." The second man says, "That sounds good, I'll have some H2O too."

THE SECOND MAN DIED. s alot of heat to significantly change the water temp becuse water has nearly the highest heat capacity of
any liquid water releases alot Yeah. I brought you all the way out here to tell you that water is made of of the elements, hydrogen and oxygen. One hydrogen molecule and two oxygen molecules. of heat without the temp changing alot. Water is almost the number one liquad that can hold the
most amont of heat. SOLAR WARMTH large bodies of water serve as reservois of solar warmth,
which prevent the weather from getting too cold or hot. however
in the desert there is vary little water so the temp is NOT
moderated. That is why the days are really hot and the nights are vary cold. Water is called the universal solvent because it can dissolve or dissociate most compounds.
A solute is the substance that gets dissolved in another substance.
The solvent is the liquid capable of dissolving other substances.
The solution is when a solid, liquid, or gas gets disperced in another solid, liquid, or gas without a chemical change. Polar: Being OR having a molecule when there is an unequal share of electrons, the negative charges.
Nonpolar: The poor little thing that lacks a permanently dipolar molecule, so it cannot bond with polars, only with nonpolars.

Some examples of solids, liquids, and gases dissolved in water are:
Salt dissolved
Sugar dissolved
Food colouring mixed/dissolved
Lemon juice mixed/dissolved
O2 being bubbled into fish aquarium water
CO2 in a soda pop Water's ability to dissolve substances depends on its polarity. For example, Kool-Aid mixed with water would dissolve, because they are both polar. If water and oil were mixed, the oil would separate from the water and float to the top, because it is nonpolar. Capillary Action: The flow of water with no gravity
Surface Tension: A film on the surface of the water
Cohesion: The force that makes water molecules stick to each other
Adhesion: The force that makes water molecules stick to other molecules
Density: The mass per unit of volume
States of Matter: The distinct forms that different phases of matter take on. Three states of matter are solid, liquid, and gas States of Water in Nature:
Liquid: Has a definite volume but not a shape examples include rivers, streams and oceans
Solid/Ice: Has both definite volume and shape. It is very hard and has density of 916.8 kg -- polar ice caps and glaciers are examples
Gas: Is free form and does not have definite volume or shape -- water vapor in nature -- humidty
