-
A molecule that has electrically charge areas.
polar molecule
-
The home or environment a plant, animal or organism lives.
habitat
-
able to dissolve other substances.

-
The tightness across the surface of water is...
surface tension
-
is the movement of a liquid through or along another material against an opposing force, such as gravity. ... Examples of capillary action in water include water moving up a straw or glass tube, moving through a paper or cloth towel, moving through a plant, and tears moving through tear ducts.
Capillary action
-
A mixture that forms when one substance dissolves into another.
solution
-
How do clouds form?
tiny airborne particles of water vapor condense into liquid or ice on the surfaces of dust particles in the air. As more water vapor condenses into water droplets, a visible cloud forms
-
The process of a substance in a liquid state changing to a gaseous state due to an increase in temperature and/or pressure.
Evaporation
-
The conversion of a vapor or gas to a liquid.
Condensation
-
The heat required to raise the temperature of the unit mass of a given substance by a given amount (usually one degree).
specific heat
-
The process by which plants give off water vapor through their leaves.
transpiration
-
Rain, snow, sleet, or hail that falls to the ground.
precipitation
-
The cycle of processes by which water circulates between the earth's oceans, atmosphere, and land, involving precipitation as rain and snow, drainage in streams and rivers, and return to the atmosphere by evaporation and transpiration.
Water cycle
-
Water in the form of a gas.
Water vapor
-
Water held underground in the soil or in pores and crevices in rock.
groundwater
-
The process of supplying water to areas of land to make them suitable for growing crops.
irrigation
-
Land consisting of marshes or swamps; saturated land.
wetland
-
Temperatures at which water changes state.
- But if we lower the temperature below 0 degrees Celsius, or 32 degrees Fahrenheit, water changes its phase into a solid called ice. Similarly, if we heat a volume of water above 100 degrees Celsius, or 212 degrees Fahrenheit, water changes its phase into a gas called water vapor.
- Water vapor changes back into a liquid at 100 degrees Celsius.***
-
Distribution of earth's water.
Only 3% of water on the surface is fresh; the remaining 97% resides in the ocean. Of freshwater, 69% resides in glaciers, 30% underground, and less than 1% is located in lakes, rivers, and swamps.
-
Why is water called the universal solvent?
And, water is called the "universal solvent" because it dissolves more substances than any other liquid. ...
-
What are the main sources of water available for human use?
- Fresh water includes water in ice sheets, ice caps, glaciers, icebergs, bogs, ponds, lakes, rivers, streams, and even underground water called groundwater.
- Ponds, lakes, rivers, and streams are our main sources as we cannot easily get to the rest.
-
Explain water's capacity to heat.
Water has a high specific heat capacity which we'll refer to as simply "heat capacity", meaning it takes more energy to increase the temperature of water compared to other substances.
