of all three trials. Heat tends to increase the rate of chemical reactions‚ explained in the article Temperature Effects (Introduction to Enzymes) by Chris Jamison. “Like most chemical reactions‚ the rate of an enzyme-catalyzed reaction increases as the temperature is raised. A ten degree rise in temperature will increase the activity of most enzymes by 50 to 100% . Variations in reaction temperature as small as 1 or 2 degrees

Environment Temperature Control Using Modbus and RS485 Communication Standards Abstract – This paper reports an undergraduate engineering team’s effort to develop a system which emulates a curing process chamber found in many industry settings. Based on industry utilization of bus protocols‚ it has been determined that the de facto standard Modbus protocol under the industry recommended standard interface RS485 is an appropriate communication method for this closed-loop control system.

These are important in determining the wellbeing of a patient because they display in numbers how one is feeling or reacting to certain medications and treatments. There are “norms” or normal numbers and when a patient

Abstract: This lab tests how temperature and pH affect how enzymes will function. The lab showed that temperature will denature an enzyme when past its optimal working temperature and won’t denature in cold temperatures‚ but have slowed molecular activity. pH will also have an affect on an enzymes efficiency‚ when out of optimal pH the enzyme will not function as it is supposed to and if to far out of the optimal pH the enzyme will change shape and no longer work. Enzymes also showed to be reusable

How does water temperature affect the amount of dissolved oxygen? Ⅰ. Introduction Dissolved oxygen is just one of the many ways to measure water quality. It means the volume of oxygen that is contained in water. The amount of dissolved oxygen in water usually determines the quantity of organisms living in that water. Dissolved oxygen levels vary by how much oxygen the water can hold‚ how much oxygen is produced by photosynthesis‚ and how much oxygen is consumed by respiration. If water is too warm

2 Angles make a difference Aim The aim of this experiment is to test whether the angle of sunlight affects the surface temperature on earth. Hypothesis I believe Block B will receive more sunlight than Block A‚ because the lamp shines directly onto Block B. Materials * * Lamp * 2 thermometers * 2 blocks of wood * Black plastic tape Procedure 1. Cut out two small identically sized pieces of black tape and attach onto wooden blocks so that they make pockets. 2.

Investigation – Storage conditions of Bleach & it’s relation with temperature. Title/Research Question: ‘How does temperature effect the concentration of chlorate ions in bleach?’ Aim: The aim of this experiment was to investigate the optimum temperature storage conditions of bleach’s stored at different temperatures. Introduction: Chlorine bleaches are made by dissolving chlorine in sodium hydroxide solution. They have a number of uses as they are used to remove colors‚ whiten or disinfectant

My final device was simple‚ yet effective. It consisted of a straw pyramid in a bag of popcorn. Two of the main restrictions for this project were mass and size. The bag that i put my materials in was within the size limit. The mass of popcorn and straws is very little. Popcorn can also absorb a lot of shock‚ stress‚ and kinetic energy. Straws absorb energy as well. So I decided to use those two materials. First‚ I put the egg directly into a pyramid of straws. Putting the egg in the pyramid instead
