EXPERIMENT 3: ISENTROPIC EXPANSION PROCESS Objective In order to demonstrate the isentropic expansion process. Introduction Isentropic means no change in entropy. Entropy is a thermodynamic property that is the measure of a system’s thermal energy per unit temperature that is unavailable for doing useful work. In simple terms‚ the measure of the level of disorder in a closed but changing system‚ a system in which energy can only be transferred in one direction from an ordered state to a disordered

Cell phones are the way of life today. In the US‚ little kids are carrying around the newest iPhone versions. Closing the digital divide requires studying and learning about the country’s needs and capabilities of upgrading to the digital world. There are countries that are financially unable to afford a cell phone‚ but it should be the cell phone companies that should be able to work around various prices for cell phones. For example‚ in the U.S. the iPhone is taking over and consumers require the

Eukaryotic cells contain its DNA within its nucleus‚ while prokaryotic cells keep it within the nucleoid. Prokaryotic cells are also more minute than the eukaryotic cells. Also although they both contain ribosomes‚ they are composed differently. 3. The central vacuole (takes in water and chemicals)‚ cell wall (allows the plant to be strong enough

Course Project: The Racial Divide in Crime Kaylyn M. Williams DeVry University According to a recent article in the Huffington Post‚ “One in every three black males can expect to go to prison at some time in their life…” (Huffington Post). This fact in itself is staggering‚ but when you compare it to the fact that only one in six Latino males and one in 17 white males will be incarcerated it is alarming. It begs the question why? Why are black males so much more likely to end up in prison

be used repeatedly. Cells have special catalysts called enzymes‚ which are specialized proteins that help accelerate chemical cell reactions. (Evert‚ RF & Eichhorn‚ SE 2013). Enzymes also control plant metabolic processes such as respiration (Evert RF‚ Eichhorn SE & Perry JB 2013). This experiment focuses on the enzyme catalase. Catalase breaks down hydrogen peroxide into water and oxygen. Hydrogen peroxide is a waste product of cell metabolism that can be toxic to the cell (Evert RF‚ Eichhorn SE

Portfolio The Cell and Cell Theory [pic] The cell The word cell comes from the Latin word “cellula”‚ which means a small room. The cell is the smallest unit of a living organism‚ also known as “the building block of life”. Every living organism is consisted of a cell. There are bacteria (unicellular organisms)‚ and multicellular organisms. There are different types of cells‚ prokaryotic and eukaryotic cells. All cells come from preexisting cells. “Every cell is self-maintaining;

Diffusion in Cells Isabel Zak Question: How does the size of a cell affect the distribution of chemicals throughout the cell? Hypothesis: The larger the cell is‚ the more difficult it will be for the chemicals to reach the centre of the cell‚ and diffuse throughout it. This is because there will be a higher surface-area to volume ratio in the larger cells‚ making the centre of the cells further away from the surface. Therefore‚ when dipped in sodium hydroxide‚ the larger cells will not be
