Lecture Presentations byNicole Tunbridge and Kathleen Fitzpatrick Chapter 3Water and Life The Molecule That Supports All of Life Water makes life possible on Earth Water is the only common substance to exist in the natural environment in all three physical states of matter Water?s unique emergent properties help make Earth suitable for life The structure of the water molecule allows it to interact with other molecules ? 2017 Pearson Education, Inc. Concept 3.1: Polar covalent bonds in water molecules result in hydrogen bonding In the water molecule, the electrons of the polar covalent bonds spend more time near the oxygen than the hydrogen The water molecule is thus a polar molecule:The overall charge is unevenly distributed

The Biological Importance of Water B io F actsheet September 1998 Number 30 1 Water is a polar molecule i.e. it has both positively charged and negatively charged areas. Water is made up of two positively charged hydrogen atoms and one negatively charged oxygen atom (Fig 1). Water (H2O) is the most abundant molecule in cells, whole organisms and on earth. This is a consequence of the unique physical and chemical properties of water. This Factsheet will briefly explain the significance of these physical and chemical properties, then discuss the primary roles of water in animals and plants. As a result of this polarity (the uneven distribution of charges), adjacent water molecules are attracted to and become bonded to each other. The

Chemical polarity

Water is Special Polarity There are two types of covalent bonds, polar and nonpolar While nonpolar molecules share electrons equally, polar molecules do not. This results in one part of the molecule being partially positive and another part being partially negative. 2 Student Misconceptions and Concerns

Chapter 10 Gases James F. Kirby Quinnipiac University Hamden, CT Lecture Presentation ? 2015 Pearson Education, Inc. 1 Characteristics of Gases Physical properties of gases are all similar. Composed mainly of nonmetallic elements with simple formulas and low molar masses. Unlike liquids and solids, gases expand to fill their containers. are highly compressible. have extremely low densities. Two or more gases form a homogeneous mixture. Gases ? 2015 Pearson Education, Inc. 2 Properties Which Define the State of a Gas Sample Temperature Pressure Volume Amount of gas, usually expressed as number of moles Having already discussed three of these, we need to define pressure.

Gas Laws -study the relationships that exist between pressure, volume, temperature and amount (moles) of gas. Boyle?s Law Pressure-volume relationship At constant temperature and amount, the pressure and volume of a gas are inversely proportional. As pressure increases, volume decreases. P1V1=P2V2 Charles? Law Temperature-volume relationship At constant pressure and amount, the temperature and volume of a gas are directly proportional. V1/T1=V2/T2 Gay Lussac?s Law Pressure-temperature relationship Under conditions of constant volume and amount, the temperature and pressure of a gas are directly proportional. P1/T1=P2/T2
