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. Gases ? 2015 Pearson Education, Inc. Pressure is the amount of force applied to an area: Pressure

Chapter 3 Chemical Reactions and Reaction Stoichiometry James F. Kirby Quinnipiac University Hamden, CT Lecture Presentation ? 2015 Pearson Education, Inc. Stoichiometry The study of the mass relationships in chemistry Based on the Law of Conservation of Mass (Antoine Lavoisier, 1789) ?We may lay it down as an incontestable axiom that, in all the operations of art and nature, nothing is created; an equal amount of matter exists both before and after the experiment. Upon this principle, the whole art of performing chemical experiments depends.? ?Antoine Lavoisier ? 2015 Pearson Education, Inc. Chemical Equations Chemical equations are concise representations of chemical reactions. Stoichiometry ? 2015 Pearson Education, Inc. 3 What Is in a Chemical Equation?

Chapter 9 Solids and Fluids States of Matter Solid Liquid Gas Plasma Solids Have definite volume Have definite shape Molecules are held in specific locations By electrical forces Vibrate about equilibrium positions Can be modeled as springs connecting molecules More About Solids External forces can be applied to the solid and compress the material In the model, the springs would be compressed When the force is removed, the solid returns to its original shape and size This property is called elasticity Crystalline Solid Atoms have an ordered structure This example is salt Gray spheres represent Na+ ions Green spheres represent Cl- ions Amorphous Solid Atoms are arranged almost randomly Examples include glass Liquid

How Are Fungi Important In Nature? Raven St. Jean Fungi play a major role in both nature and society in the sense that they are a huge resource for many things, like medicine. Fungi serve a purpose to the earth, humans, and many animals and plants. First, fungi are very beneficial to life on earth by recycling material. Without bacteria and fungi, gardening plants would be impossible. They lock up plant nutrients until they?re needed and can be used by the plants. This act reduces leeching of vital nutrients from the soil and makes a great home to plants. They also retain water in the soil for plants. The greatest deed that fungi do is act as a decomposer and break down dead matter into components that other plants and animals can eat.

Ecology-A Study of Relationships Ecology means the study of the home Ecology is the study of organisms in their natural environment Biosphere is everywhere that life exists Viewing planet Earth from Space Satellites are an economical way to gather data; they have sensors, these gather data quickly from a very large region, and they last a long time Electromagnetic radiation Total ozone-mapping spectrometer Understanding environmental interactions allows us to predict the effects of human activity Biomes- Climatic Zones of Life Biome- a large geographic region determined by the climate and soil type Climate- average weather pattern over a long period of time Ecosystem- a Functional Unit Ecosystem is the Functional Unit because biome is too big to conduct research
