Total kinetic energy due to molecular motion in a body of matter. Conversely, one calorie is the amount of heat that one gram of water releases when it cools down by one degree Celsius. A liquid that is a completely homogenous mixture of two or more substances. Substance dissolved in a solution. Solution in which water is the solvent.
Water is a versatile solvent owing to the polarity of the water molecule.
Charged regions of polar water molecules have an electrical attraction to charged ions. Water surrounds individual ions, separating and shielding them from one another. Charged regions of polar water molecules have an affinity for oppositely charged regions of other polar molecules. Solute concentration in aqueous solutions. Most biochemical reactions involve solutes dissolved in water.
