To design an electrochemical cell that produces an optimal energy output?
Temperature
Heat
Energy
Voltages produced by the galvanic cell would decrease in intesity as the temperature increases as both the voltage and the temperature are proportionally inverse.
To what extent can temperature impact the intesity of which a electrochemical cell can output energy?
Practical
Equipment
Beaker
measuring cylinder
Cu
iron strip
Zn
zinc strip
copper strip
aluminium strip
Variables
independent variables
The nature of the metal(Types of metal used/Metal reactivity.
Controlled Variables
Dependent Variable
Uncontrolled variables

factors
Concentration
As concentration increases so does the volatage for al 3 types of cells.
The concentration of ions in solution affect the cells potential
Increasing the concentration of reactants increases the voltage difference. A higher concentration of reactants allows for more reactions I the forward reaction sits it reacts faster.
Temperature
As temperature increases sp does the voltage for all 3 types of cells.
The temperature determines the cells potential
Surface Area
When surface area increases so does the voltage for both cells
Nature of Metal (Metal reactivity)
Galvanic/voltaic cell
Measure
How are we measuring?
To measure a electrochemical cell we will use a voltmeter, placing it on the wire.
What are we measuring?
We are measuring the electrochemical current and the potential.
conductors
copper
gold
aluminum
The free-flowing delocalised electrons in the golds atoms act as free charge carriers which help the conduction of electricity within a voltage source.
