Temperature Changes - GCSE Science Required Practical
Exploring the temperature changes in an exothermic reaction.
Analysis and conclusion
a. Calculate the mean maximum temperature reached for each volume of sodium hydroxide.
Record these means in your table.
b. Plot a graph from your results and draw two straight lines of best fit.
c. From the graph read off the maximum temperature change.
d. This is an example of an exothermic reaction, when heat is given out. Can you explain why the results you recorded show that the temperature started to fall after a certain volume of sodium hydroxide had been added?
