Worked Solution & Example Answer:The apparatus shown is used in a first-hand investigation to determine and compare the heat of combustion of three different liquid alkanols - HSC - SSCE Chemistry - Question 5 - 2009 - Paper 1
Step 1
Independent Variable
Answer
The independent variable in this investigation is the factor that is intentionally changed to observe its effect on the dependent variable. In this case, the independent variable is the type of alkanol used, as this will affect the heat of combustion measured in the experiment. Therefore, the correct answer is (A) Type of alkanol used.
