The effect of temperature on conductivity and resistance
_____________________________________________________________________________________
INTRODUCTION
Hypothesis:
So, I think that when the temperature of my wire increases, the resistance of the wire will also increase making the conductivity of the wire reduce. I believe that the opposite would happen if there was a decrease in temperature.
Explanation:
Conductivity is the inverse of resistance.  The higher the resistance of the wire, the lower the conductivity will be. I am almost certain that temperature of the wire increases due to a power loss. The more current in the wire or even a higher amount of resistance will cause the temperature of the wire to increase. So, this basically tells me that the size and material of the wire will affect the experiment.
Research:
So why would resistance increase?
My reason of resistivity can be explained through the flow of current through the material. (Flow of current = The movement of electrons from one atom to another
Method
Materials:
-5m of Copper Wire with selected diameter (this experiment uses 0.5mm)
-Two 300mm PVC pipes

-Ammeter
-A plastic knife
-Thermometer
-Insulation tape (black tape)
Extraneous Variable:
STEPS:
1. Firstly, wind your copper wire around the PVC pipe.
2. Tape the ends of the...

Investigating the Effect of Temperature on the Permeability of Membranes

1928 words - 8 pages Investigating the Effect of Temperature on the Permeability of MembranesThe permeability of membranes can be altered in several ways. From previous preliminary work I know that reagents, for example detergents and alcohol alter the arrangement of the phospholipids in the membrane allowing substances to leak out of the cell. Temperature also affects the membrane. As membranes relay on protein molecules to allow molecules to enter and leave the

The Effect of Temperature on the Permeability of Beetroot Membrane

1307 words - 5 pages The Effect of Temperature on the Permeability of Beetroot Membrane Analysis The graph shows the colorimeter readings increase as the temperature increases, they increase by the most at higher temperatures. This is shown by a smooth curve. This means that the beetroot samples release more dye at higher temperatures. This is because higher temperatures cause the membrane structure to break down. The membrane

THE EFFECT OF TEMPERATURE ON THE RATE OF ENZYME ACTIVITY

651 words - 3 pages testing the temperature on the rate of enzyme activity is to examine how different temperature might increase or decrease activity. Adding energy in the form of heat to the enzyme will most likely increase activity because more reactions are able to take place. However, cooling down the enzyme and thus removing energy will most likely slow down the process because there is less energy available for the enzymes to utilize for reactions. However

Dependent variable Catalase enzyme activity (measured as % of oxygen produced) Independent variable 1 experiment: pH 2 experiment: temperature Controlled variable Amount of time The purpose of this lab was to determine the effect of pH and temperature on the rate of catalase enzyme activity. Since the catalase speeds up the

Biology: Experiment- The Effect of Temperature on the Enzyme Rennin

1890 words - 8 pages Aim: The aim of the experiment is to test the effect temperature has on the activity of the enzyme rennin.Hypothesis: I believe the rate of reaction will speed up as the temperature increases until it reaches about 37oC, which is the body temperature, where it will begin to slow down and stop reacting. I believe this will occur because enzymes have a temperature range at which they work best in and once the temperature goes out of this range the

The Effect of Temperature on Anaerobic Respiration of Yeast

The purpose of this lab was to demonstrate the effect of temperature and germination or nongermination on cell respiration and the relationship between dependent and independent variables. The following materials are needed to perform the lab: * 20 germinating peas * 20 dry peas * 30 glass beads * Potassium Hydroxide 15%, 6mL * 2 waterbaths * 6 respirometers (glass vials, graduated pipets, one

Investigate the Effect of Temperature on Cell Membranes and Membrane Structure

2132 words - 9 pages Investigate the Effect of Temperature on Cell Membranes and Membrane Structure If you read a recipe for cooked beetroot it will usually recommend that you don’t remove the outer skin of the beetroot and don’t cut off al the stalk and root if you want to avoid getting lots of red dye in the cooking water. Beetroot contains red pigments called betalains, located within the cell vacuole. Normally the pigments can’t pass through membranes

Procedure to Investigate the Effect of Temperature on Beetroot

717 words - 3 pages Aim: to investigate the effect of temperature on the cell membrane structure. Hypothesis: I predict that more concentration of betalains will be released as the temperature increases because the temperature will soften the cell vacuole and cell membrane allowing more betalains to pass through. Introduction: Beetroot contains red pigments called betalains, located within the cell vacuole. Normally the pigments cannot pass through the
