June 2014 Examination: Additions/Corrections/Alternatives to memoranda

Grade 11 examination paper

London forces and dispersion forces can be accepted as well.

V1 = 4 000 cm^3 or V2 = 0,005 dm^3
Answer = 48 000 kPa

V1 = 8 000 cm^3 or V2 = 0,005 dm^3
Answer = 48 000 kPa

For clarity: The broken line represents the answer at lower temperature.

Additional correct answers (variations on those in the memo):

Typing error. Where the net force is calculated, the last part should be squared, i.e.:
(8,64 x 10^-5)^2

"monomer" may NOT be used in the definition as a substitute for "molecule".

Structural formulae MAY be used since the question did not specify what kind of a structure is needed.

Totals in memo should be 22, 18 and 21 marks respectively.

Negative marking applies to all the above-mentioned questions.
