proceeded to conduct this experiment to find the relation between temperature of solubility‚ molar mass and ionic radius. Intermolecular forces had sparked interest in me from the very day it was begun to be taught. I have chosen all nitrate salts only as I wanted to compare my temperature results with the ionic radius of the metallic element in the compounds. Background information: As previously taught‚ I know that the temperature of solubility of a salt will be higher if the molar mass of a substance

BIOL 152-35 Professor Weller 14 February 2012 Effects of Temperature on Goldfish Respiration Introduction This experiment was designed to identify the effect of cold-water temperatures on the respiration rate of goldfish. The respiration rates helped to identify the goldfish as being ectotherms or endotherms. Organisms exchange gases with their environment through a process called respiration or breathing. Aerobic respiration‚ also known as aerobic metabolism‚ occurs when oxygen is taken

steel rod with a cross-sectional area of 0.25 in2 is stretched between two fixed points. The tensile load at 70°F is 1200 lb. What will be the stress at 0°F? At what temperature will the stress be zero? Assume α = 6.5 × 10-6 in/(in·°F) and E = 29 × 106 psi. Solution 261 For the stress at 0°C: answer For the temperature that causes zero stress: answer problem 262 A steel rod is stretched between two rigid walls and carries a tensile load of 5000 N at 20°C. If the allowable stress

Animal Behavior of Isopods 1a) Do terrestrial isopods prefer to stay in a cold or warm environment that is in a neutral (room temperature)‚ mild‚ or extreme temperature difference from room temperature? 1b) If the isopods prefer to be in a mildly warm environment‚ then when they are randomly placed between a warm and cool chamber with only one warm and cold pack (mild temperature difference) on each end of the chamber and are able to move freely‚ they would prefer to move to the mild warmer side of the

feeding on dead and moribund animal matter. For this reason‚ it is considered an important commercial cleaner’ of our seashores. Temperature fluctuations in this habitat are habitual to the whelks. In my initial research‚ I found out that there isn’t any evidence of a type of feeding activity rhythm shown by the whelks and then I thought to investigate if temperature affected what time they fed and hence their feeding activity period.

raising the temperature. Stir with a glass rod occasionally to make sure the heating is uniform. Measure 50mL of cold distilled water and place in the calorimeter setup. As the water is heating‚ also monitor the temperature of the cold water to find when it reaches equilibrium. Record the temperature of the cold water to the nearest 0.2°C. When the water being heated reaches 70°C-80°C‚ remove from the heat and let it sit on the lab bench‚ stirring occasionally. Record the temperature of the hot water

experiment was to find out how temperature affects the enzymes activity. For example‚ in Humans if the temperature is too high‚ the individual’s brain enzymes can denature and cause life threatening problems. The opposite can occur as well‚ if the temperature is too low‚ hypothermia can occur and it can be dangerous (Wilson‚ 1996). In the experiment optimal conditions for fungal and bacterial amylase was measured as well. Discovering information‚ such as the optimal temperature‚ can help demonstrate the

Effects of Temperature on Enzyme Biology Introduction In order to understand the activity of enzymes at different temperatures the ability of the enzyme to function can be measured. This is important in many applications such as Polymerase Chain Reaction for forensics as well as genetics research where manipulation of temperature-dependent enzymes allows for replication of DNA segments. Bennett states‚ “when the energy - measured

control the temperature in the living room‚ just with single button the room temperature can be controlled automatically so when the room temperature is too cold the heater will operate to produce a regulated temperature and when the room temperature is too high the cooling system will operate to produce the desired temperature. 1.2 Objectives: There are four objectives to be achieved in this project. Below are the following objectives: 1.2.1 To design appropriate circuit for temperature control
