QUESTION 1: MULTIPLE-CHOICE QUESTIONS
Various options are provided as possible answers to the following questions. Choose
the answer and write only the letter (A-D) next to the question number (1.1-1.6) in the
ANSWER BOOK, for example 1.11 D.
1.1. Acar of mass 1000 kg pulls a trailer of mass 500 kg as shown.
- ae
i eee, el
According to Newton’s third law of motion, which ONE of the following statements
is TRUE?
A The car and trailer pull each other with a force that is equal in magnitude
but opposite in direction. Therefore, the net force is zero and the trailer
cannot move.
B The force that the car exerts on the trailer is greater than the force that the
trailer exerts on the car. Therefore, the trailer moves forward.
Cc The action force from the car is quicker than the reaction force from the
trailer, so they move forward.
D The action-reaction forces are equal in magnitude, but the force between
the ground and wheels pushes them forward. (2)
1.2 When the momentum of an object of constant mass is doubled, then its kinetic
energy will be ...
A halved.
B doubled.
~-- 5+ ee C - -~threetimes greater- - - - - - ----- Hee Sid
D four times greater. (2)
1.3. Two objects are released from the same height at the same time. One object has
TWICE the weight of the other. Neglecting friction, which ONE of the following
statements is CORRECT for the motion?
A The heavier object hits the ground first
B The lighter object hits the ground first.
Cc Both objects hit the ground at the same time
D On hitting the ground, the heavier object has a greater velocity than the
lighter object (2)

QUESTION 6
6.1 The temperature at which the vapour pressure of a substance equals the
atmospheric pressure. (2)
6.2 163 °C (2)
6.3
The acid (A) has TWO sites for hydrogen bonding while the alcohol (B) has only
one site.
The carboxylic acid molecules require more energy to overcome the intermolecular
forces
Carboxylic acid will have a higher boiling point. (4)
6.4 Butanoic acid. (2)
6.5 LOWER.
_-
CH3(CH2)2CH2OH or butan-1-ol has a shorter carbon chain/smaller
surface area than compound B. Strength of the intermolecular forces in
CH3(CH2)2CH2OH or butan-1-ol is weaker than that in compound B.
Therefore lesser energy needed to separate the molecules. OR
Compound B has a longer carbon chain/ larger surface area than CH3(CH2)2CH2OH
or butan-1-ol The intermolecular forces between molecules of compound B
are therefore strongerand require more energy to separate the molecules. (3)
