How can we recognize when we have made progress in the search for knowledge? Consider two contrasting areas of knowledge. The search for knowledge is a constantly ongoing process. So how are we to know if we have made any progress? Progress is development‚ advancement‚ and moving forward. In this case it is the progress in the search for knowledge in an area of knowing. Within the areas of knowing the strongest contradiction is between human science and natural science. Human sciences

Debbie Cao IB Chemistry 12 Pressure/Volume of Air Full Lab Write Up Introduction: According to Boyle’s Law‚ the volume of any given amount of gas held at a constant temperature varies inversely with the applied pressure. In other words‚ when the pressure increases the volume decreases. When pressure decreases‚ volume increases. This can be derived from the following equation: P1 V1=P2 V2 The common use of this equation is to predict how a change in pressure or volume will alter the

Chemical Reactions and Equations Chemical Reaction: The transformation of chemical substance into another chemical substance is known as Chemical Reaction. For example: rusting of iron‚ setting of milk into curd‚ digestion of food‚ respiration‚ etc. In chemical reaction new substance is formed which is completely different in properties from the original substance‚ so in a chemical reaction chemical change takes place. Following are the signs of chemical reaction: (a) Change of state of substance

Interior and Spatial Design 2010 My interest in space‚ design and architecture led me to choose this slightly more unique and diverse essay title. In this essay I chose to look in depth at the connection between pieces of interior or spatial design with more traditional pieces of art such as paintings. I wanted to explore how a space or room can be seen as art and how it can create moods and feelings just as strongly and easily and traditional pieces. A particular piece of spatial design that greatly

Abstract: The Enzyme Lab results where when the liver was frozen‚ its reaction was fast‚ and when it was hot‚ it was slow‚ and the liver that was at room temperature reacted slowly to medium. Introduction: The Enzyme Lab is to conduct investigations to determine the most favorable conditions for the most efficient enzyme activity. Variables to be used testing include temperature‚ pH values and surface area. Enzymes are proteins that speed up the rate of chemical reactions‚ which would otherwise

RATE OF REACTIONS. The reaction rate (rate of reaction) or speed of reaction for a reactant or product in a particular reaction is intuitively defined as how fast or slow a reaction takes place. For example‚ the oxidative rusting of iron under the atmosphere is a slow reaction that can take many years‚ but the combustion of cellulose in a fire is a reaction that takes place in fractions of a second (right). Chemical kinetics is the part of physical chemistry that studies reaction rates. The concepts

Dead or Alive II Pre-Lab 1.In order to find the article‚ I first went to Google Scholar and set my search parameters for articles published from 2010-2013. I then decided to use the keywords “deep sea trench life” to pull up a broad spectrum of articles pertaining to the types of life we would be discovering in our samples. I then browsed each article’s title to determine if it contained relevant information to the topic at hand. 2.After finding a suitable article‚ I then went through the parameters

Chapter 1 Chemical Reactions and Equations Q.1. Why should magnesium ribbon be cleaned before burning in air ? Ans: Magnesium ribbon is a very reactive metal. When stored it reacts with oxygen to form a layer of magnesium oxide on its surface. This layer of magnesium oxide being a stable compound prevents further reaction of magnesium with oxygen. The magnesium is cleaned before burning in air to remove this layer so that the metal can be exposed to air properly. Q.2. Write the balanced
