Water is the most classical to living organisms. It makes up 70 to 95 percent of most organisms. Water is flexible because it is north-polar. A polar molecule is a molecule with an unequal distribution of charge. That essentially means one end of the molecule has a domineering charge and on end has a negative charge. table salt will brush aside into water because polar molecules will dissolve other polar molecules. Hydrogen subdivisions attract to the oxygen atom because of hydrogen bonds. Water changes temperature slowly because it resists temperature change. Water therefore releases scads of energy in the form of heat when it cools. This property tar score keep cities warm or cool. Water is very important to cellular functions of aquatic organisms. Water is also able to place substances in living organisms.
Water is less dense when it freezes and turns to ice when in its liquid form. That is why icebergs float in the sea. A piteous particle moves in a straight line until it collides with some other particle. Diffusion is the net movement of particles from an area of high density to an area of lower concentration. It is a very slow do by because it relies on the random motion of atoms and molecules. The three factors that affect airing are pressure, temperature and concentration. Pressure and temperature are both external forces.
If temperature or pressures are increased, the diffusion rate will also increase. fighting(a) equilibrium occurs in biological substances. For example, oxygen diffuses into the capillaries of the lungs. There is a higher concentration of oxygen in the air sacs of the lungs than in the capillaries.
Water is made of two hydrogen and one oxygen, so called H2O. A French chemist named Antoine Laurent Lavoisier said that water was not an fraction but rather a compound of...If you want to get a full essay, order it on our website: Ordercustompaper.com
