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
Which is the independent variable?
Answer
The independent variable in this investigation is the factor that is changed or manipulated to observe its effect on the dependent variable. In this case, the different types of alkanols being used directly influence the heat of combustion that is measured. Therefore, the correct answer is:
(A) Type of alkanol used.
