Chapter 1 1. Define sustainability. What role does concern for future generations play in the notion of sustainability? The ability for a society to meet the needs of the present generation without compromising the ability of future generations to meet their own needs 2. Distinguish between natural resources and environmental services. Natural resources – we get from the environment to meet our biological and economic needs and wants Environmental services – natural processes

objects for insulation because black will radiate the heat greatly. I have found information from the internet‚ that the polystyrene will be the best in insulator. I will have to bung up the end of the test tube as well because heat will be lost by convection currents. By keeping the test tubes well insulator the water molecules should be zooming around in the water at the same speed for a longer time with all that trapped heat energy. Prediction I predict that polystyrene will be the best insulator

Chapter One Introduction to Geology "study of the Earth." Geology literally means Physical geology examines the materials and processes of the Earth. Historical geology examines the origin and evolution of our planet through time. • Geology is an evolving science - the theory of plate tectonics was just accepted in the 1960’s. • • . Geology seeks to understand the origin of our planet and our place in the Universe - answers to these questions are also posed outside of the realm

determine the net heating or cooling load. Heat Gain From People Typical sensible‚ latent and total heat rates given off by people are shown in the table below (ASHRAE Fundamentals‚ 2005). The sensible heat gain results from radiation and convection from the human body to the air. The latent heat gain is the energy required to condense the water vapor given off by human respiration and perspiration. The latent heat gain is the product of the mass of water vapor from humans and the enthalpy

Flame Main article: Flame A candle’s flame Photo of a fire taken with a 1/4000th of a second exposure A flame is a mixture of reacting gases and solids emitting visible‚ infrared‚ and sometimes ultraviolet light‚ the frequency spectrum of which depends on the chemical composition of the burning material and intermediate reaction products. In many cases‚ such as the burning of organic matter‚ for example wood‚ or the incomplete combustion of gas‚ incandescent solid particles called soot

Large cities have their own climatic conditions. To what extent is this true? (40 marks) Large cities have their own climatic conditions and can be referred to as having a micro-climate. Micro-climates are small scale variations in temperature‚ precipitation‚ humidity‚ wind speed and evaporation that occur in an environment. This would therefore suggest that the statement is in fact true. Large cities create their own climate and weather which is known as the ‘urban climate dome’ within which weather

Looking at the world we live in today‚ many things that we have or use are taken for granted. We don’t think much about how a telephone works when we’re talking to our friends‚ or how emails and faxes can travel from one unit to another within a blink of an eye. When we go inside our homes and turn on our TV’s‚ do we ever wonder how the human mind could ever comprehend radio waves and electromagnetic energy? How were these things invented? How did anyone get the first ideas to experiment? After all

The market revolution era of good feelings began in the first half of the 19th century 1793-1860 where we see a shift from a self-sufficient agrarian society where farmers would produce for themselves to producing goods for sale that would change how Americans do business. During the market revolution we see a rise of two different type of industries between the north and the south‚ the north became an industrialized society with the factory system which allowed for mass production of goods‚ allowed
