water properties and benefits
High Surface Tension
Water appears to have a "skin" on surface b/c water molecules stick together (cohesion)
Universal Solvent
Water dissolves more substances than any other solvent
universal solvent
a liquid that can dissolve into anything - Water
heat of vaporization of water
amount of energy needed to change 1 gram of the liquid to a gas
atoms that make up water
an oxygen atom and two hydrogen atoms (h2o)
benefit of water's high heat capacity
aquatic animals can use water as a habitat
Solid, Liquid, Gas (density)
how much matter or mass is inside an object
benefit of water being able to have different densities
if it was all the same density, it can freeze and sink to the bottom of a body of water, causing them to freeze from the bottom up, effectively killing all life in water
benefit of water's adhesion property
it allows capillary action to occur, which helps plants and trees access nutrients needed to survive
benefit of water's cohesion property
it allows plants to receive necessary fluids
benefit of water being a universal solvent
it can take valuable chemicals, minerals, and nutrients as it travels through things, giving living things necessary substances
benefit of water's high surface tension
it stays together, allowing plants to receive water without it spilling over and makes life easier for organisms
benefit of capillary action
water can travel up from the roots of trees and plants, spreading the valuable nutrients to the rest of the tree/plant
significance of water being a polar molecule
water is attracted to other molecules that contain an electrical charge, which gets dissolved
High Vaporization Point
Amount of energy needed to change 1 gram of the liquid to a gas - Water has a high HoV; it evaporates slowly
High Specific Heat
Amount of heat needed to increase the temperature of 1 gram of a substance by 1° C. - Water has a high specific heat; it takes a lot of energy to change temperature
Capillary Action
Water's ability to move upward, against gravity, through really small openings
Adhesion
Water's ability to stick to other molecules of a different substance
Cohesion
Water's ability to stick to other water molecules
benefit of water's high boiling point
living organisms do not have to drink boiling water allowing them to live and all the water in the world will not evaporate so quickly
