container that holds it. Like a liquid a gas has no fixed shape‚ but it has little resistance to compression because there is enough empty space for the molecules to move closer. Whereas a liquid placed in a container will form a puddle at the bottom of the container‚ a gas will expand to fill the container. Although the three categories seem very well defined‚ the borders between the different states are not always clear. Apart from the three familiar states‚ there exist a large number of other intermediate

Korenkova Alexandra Essay on topic: Learning organizations in global environment: do they exist? In today’s dynamic and unstable operating conditions of enterprises the ability to innovate is a key factor of survival and success of the organization. Innovations in this case are understood in a broad sense – it means not only to create and offer a new product‚ but rather the ability of the organization continually develop creative solutions to problems and challenges. In this regard‚ the role

What Every Muslim Teenager and Adult Needs to Know About Sexuality Everywhere in this society‚ sex‚ and sexuality are openly displayed for all to see. In this climate of free sex and loose moral standards‚ it becomes imperative for Muslim parents to be proactive in the sexual education of their children. Now‚ although for many of us‚ the thought of telling our children the whys‚ how‚ and where of the proper sexual behavior between a man and woman might make us cringe‚ when we think of the alternative

of solvent extraction‚ also known as liquid-liquid extraction‚ a method of separating two materials with different physical and/or chemical properties. Two methods of evaporation will be used to finally determine the concentration of impurity- one using an explosion-proof hot-plate‚ and one using a rotovap. III. Theory Fig. 1a+1b. Figure 1a shows how water and oil separate in the separatory funnel‚ while figure 1b shows the actual apparatus. Liquid-Liquid extraction is a versatile and dependable

Why Do Living Things Need Energy? All living things need energy to survive. Nearly all the energy for life comes from the sun. Autotrophs are organisms that make their own food. There are two laws of Thermodynamics: • First Law- The law of conservation of energy‚ which states that energy can be converted from one form to another‚ but it CANNOT be created or destroyed. • Second Law- States that energy cannot be converted without the loss of usable energy IMPORTANT TERMS Energy- the ability

LIQUID CRYSTALS Introduction What are Liquid crystals ? Its History & Discovery Any of various liquids in which molecules are regularly arrayed like a solid crystal along one or two dimensions‚ but are free in the other dimensions as with typical liquids. Liquid crystals often display unusual and often manipulable optical properties such as anisotropic scattering. They can be divided into two classes‚ Thermo tropic(nematic‚ chiral nematic‚ and smectic.) and Lyotropic. Transitions to thermotropic

Metabolisms are all the chemical reactions that the living cells and organisms use to maintain life. It also divides into two categories: Catabolism – that breakdown the molecules to obtain energy and Anabolism – that creates all of the compounds that the cells need to function. Nutrition is an important part of the availability of nutrients that utilized in the reactions that either synthesize or catabolize the material that is employed by the cells to produce power. This power is a requirement by
