Lab Report Behavior of Gases and Absolute Zero Determination Lab 4 Summary of Concepts: Through this experiment we will be investigating the differences between the gas laws. We will investigate the relationships between pressure, volume, and temperature. By the end of the experiment we will have data to prove the gas laws. The Gas Laws we will be investigating are as follows: Boyle’s Law: PV=C Charles’ Law: V/T=C Gay-Lussac’s Law: P/T=C Avogadro’s Law V/n=C Ideal Gas law: PV=nRT
hold non-committal positions, no scientific body of national or international status disagrees with this view (DiMento & Doughman, 2007). When investigating climates antecedent to human history, indirect methods are exclusively depended upon. Those used to calculate past temperatures, observe responses to past temperature change that are preserved in ice, rock and fossils (temperature proxies). Marine sediment cores also provide indication of temperature records spanning millions of years, as they
vial. Next, place the first set of germinating peas, dry peas and beads and beads alone in vials 1,2, and 3. Place the second set of germinating peas, dry peas and beads, and glass beads in vials 4,5, and 6. Insert the stoppers in each vial with the proper pipette. Place a washer on each of the pipettes to be used as a weight. Make a sling using masking tape and attach it to each side of the water baths to hold the pipettes out of the water during the equilibration period of 10 minutes. Vials
individually tailored treatment regimens that will help improve patient treatment adherence and overall treatment effectiveness (Porto, 2011; Jakšić et al., 2013; Požgain et al., 2014). However, researchers have observed that many of the correlations found between dispositional personalities traits (e.g. optimism, pessimism, acquiescence, and absorption) tend to be inconsistent (Morton et al., 2009; Whalley et al., 2008; Kelley et al., 2009; Geers et al., 2010; Turiano et al., 2012). Not only, has the majority

conservation applies to natural disasters. Energy is conserved when it changes form. Most sources of energy are diffuse: weak, but cover a wide area Disasters generally have a concentration of energy into a small area Describe relationships between force, pressure, stress, strain, energy, and power. Power: work/consuming energy per second = measured in watts Pressure: force per unit surface area applied perpendicular to a surface Stress: force per unit area applied parallel to a surface
"Fierce competition for fresh water may well become a source of conflict and wars in the future." - Kofi Annan, former U.N. Secretary-General in 2001 Background of the Study 1. Water is directly related with the survival of human kind and it is crucial unlike other resources, because it does not have choices and alternatives. As a consequence of global warming and pollution, importance of water has increased much. Some "2 billion people” already lack water supplies. Water use has risen six-fold over

Light Carbon Dioxide + Water Oxygen + Glucose Chlorophyll How to test a leaf for starch: 1. Dip leaf boiling water for about 1 minute to soften it, stop further chemical changes and make the cell more permeable. 2. Turn off Bunsen burner. Put the leaf into the half a test-tube of ethanol. Stand the test-tube in the hot water for a few minutes. (Takes green chlorophyll
is said to be specific for this substrate. There are two types of enzyme inhibitors: Competitive and Non-Competitive inhibition. If an inhibitor molecule binds only briefly to the active site of the enzyme, there is competition between it and the substrate for the active site. This means it is more likely that the substrate will collide with a filled active site and so this is known as competitive inhibition. It is said to be reversible (not permanent) because it
