Def of cohesion
The sticking together of particles of the same substance.
Def of adhesion
Bonding between h2o and other substances
Def of solvent
The liquid in which a solute is dissolved to form a solution
Def specific heat
The amount of heat energy to raise the temperature.
Def of heat of vaporization
The energy of heat or consumed during the vaporization of a liquid.
Def of concentration
Condensing
ph
Uunit of measurement that indicates how acidic or basic a substance is.
pOH
Potential of Hydroxide
Hydroxide ion
Hydrogen and oxygen bond
Hydronium ion
A positively formed with hydrogen and water bonds
Def of acid
pH of less than 7
Def of base
pH more than 7
5 properties of water
Cohesion, polarity, high specific heat, high heat of vaproization, low density of a solid.
Explain how water’s polarity or ability to make hydrogen bonds gives it each property
The polarity of water creates a positive charge on the hydrogen and a negative charge on the oxygen
Examples of why each property is important to living things
It allows for the body to cool down and regulate temperature.
Decide whether a solution is an acid, base, or neutral when given either pH, [H3O+], [OH-], or pOH
It is acidic if pH is less than 7, its neutral if the pH is exactly 7 and is basic if the pH is greater than 7.
Compare the concentrations of [H3O+] and [OH-] of solutions with two different pHs
If if you have a higher pH the lower the OH and the higher the H30
