1,324 wordsThe purpose of this lab was to find that gravity of Earth is indeed 9. 8 m / s /s (the The theory, according to Galileo, is that two objects have the same acceleration if dropped from the same height will land at the same time at the speed of 9. 8 m / s /s as long as there is no air resistance. To have an understanding Galileo's theory of acceleration, certain terms and equations must be known. Acceleration is defined as the change in velocity divided by the time interval which the change of vel...

Concentration And Reaction Rate
1,782 words... e light intensity the same throughout the entire experiment by working in the shade. Prediction: I predict that as concentration of thiosulphate increases so will reaction rate. Concentration of a reactant affects reaction rate because there are more frequent successful collisions. Assume a person has two chemicals x and y, which react when put together. If all input variables remained constant apart from concentration then fastest reaction rate possible would be to mix (assuming there isnt ...

Cumulative Frequency Diagram Lt X Lt Mins
1,566 wordsThe title of my investigation is The Average student. I am going to investigate into whether the students in my year (11) are normally distributed. I have chosen to investigate into this topic because we were required by this subject to produce a piece of coursework assignment, so we decided this would be easiest and most feasible. This leaves me with the predicament of trying measuring certain people in my year group. Are the people in my year at completely different ends of the scale or are th...

Carbon Atoms Measuring Cylinder
3,479 wordsComparing Energy Release from the Combustion of Alcohols I am going to investigate the energy released by burning alcohol called the enthalpy of combustion. I will be trying to find out how the number of Carbon atoms the alcohol contains effects the enthalpy change that occurs during combustion. The Alcohols are a series of related organic molecules where each member has the -OH (hydroxyl) group in the molecule. The general formula of an alcohol is: Cn H 2 n+ 1 OH, where n is the number of Carbo...

Fatty Acids Petri Dish
4,956 wordsPlan The initial variable to be considered will be the effect that caffeine and temperature has on the heart beat and if it has a direct or indirect effect on the daphnia's lifespan. If there is enough time to consider a second variable however, the effects of a temperature or alcohol on the daphnia's body system will also be considered alongside the initial variable of caffeine. These will then be slotted into the same graph which will show us how the figure correspond to the results. In order ...

Power Supply Magnetic Field
1,679 wordsPlanning Aim To find the factors that affect the amount of E. M. F. being produced. The amount of E. M. F. produced during the experiment when each type of factors is change. Background knowledge Electro-motive-force is the energy being supply to a charge. Battery is a type of energy. The energy that it provides is voltage. Battery voltage is sometime called electro-motive-force because it is used to pump around the electrons in the wire. The force can be generates by the moving of magnetic fiel...

Inversely Proportional Cross Sectional
1,082 wordsAim I am going to be studying the resistance of wire. The purpose of this investigation is to see how length and thickness of wire affect the dependent variable, resistance. Prediction I predict that, as the length of the wire doubles, the resistance will also double, but as the cross-sectional area of the wire doubles, the resistance halves. This means that the length will affect the resistance more than the thickness will. Hypothesis Resistance is caused by electrons bumping into ions. If the ...

Rate Of Reaction Hydrochloric Acid
1,681 wordsInvestigating The Rate Of Reaction Between Sodium Investigating The Rate Of Reaction Between Sodium Thiosulphate And Hydrochloric Acid Investigating the rate of reaction between Sodium Thiosulphate and Hydrochloric Acid Diagram Aim: We did 4 experiments to find out how the rate of reaction changes with differing concentrations of Sodium Thiosulphate, Hydrochloric Acid and water. As an inert and stable liquid, water was used to alter concentration of Sodium Thiosulphate without changing the end a...

Carbon Dioxide Liquid Nitrogen
2,011 wordsPURPOSE: In this particular laboratory experiment, we are going to determine the molar mass of an unknown gas, from the gas density. We are also going to use gas density, along with the kinetic molecular theory, to explain the behavior of gas filled balloons. Finally, we are going to demonstrate the effects of temperature and pressure changes of gasses. PROCEDURE: We are using the experimental procedure as described in our laboratory manual.

Measuring Cylinder Reaction Rate
3,430 wordsHow concentration affects reaction rate. The aim of this investigation is to see how the concentration of a reactant in ratio to the reactor affects the rate of a reaction. When hydrochloric acid and Thiosulphate react together sulphur is liberated this means that as the reaction goes on the solution will become yellow and will change from being transparent to translucent to opaque. The sulphur is formed as a solid but not in the usual precipitation way. Na 2 + S 2 + 2 HCL 2 NaCl+SO 2 + S 2 +H 2...
