Subject: Chemistry
Topic: Separating Techniques for Mixtures

Questions:
A mixture of ethanol and water can be separated using the __ separation technique.

A. fractional distillation
B. Decantation
C. evaporation
D. condensation

Answer is A

Explanations:
Ethanol (C2H5OH) and Water (H2O) are miscible liquids. A mixture of two or more liquids which mix with each other to form a homogeneous solution is known as miscible liquids. Example: mixture of ethanol and water.

Fractional distillation: It is a technique for the separation of a mixture of two miscible liquids which have comparable boiling points i.e., the difference between their boiling points is less than 25 K due to repeated evaporation and condensation. Boiling point of ethanol is 78.37oC and boiling point of water is 100oC.

Principle involved in the separation of ethanol and water:
The component with lower boiling point evaporates first and leaves the mixture due to the difference in the boiling points.
The vapours of other liquid cool and condense back to the flask due to the increased surface area for cooling available through the glass beads of the fractional distillation column. In this manner, evaporation and condensation takes place again and again.

Set-up for the fractional distillation of ethanol and water:
i. The apparatus used for fractional distillation is called fractionating column.
ii. The mixture is poured into a round bottom flask held by a clamp and placed on the burner.
iii. The mouth of the round bottom flask is fitted with a fractionating column and thermometer is placed in it.
iii. This is glass tube with glass beads that pose hindrance to the vapours of the liquid coming from the flask.
iv. A water condenser called Liebig's condenser is fitted into the side of the column. Its inner tube is connected to the flask for the liquid to pass through and cool water is circulated through its outer tube to condense the vapours coming from the round bottom flask.
v. An empty flask is placed at the other end of the condenser to collect the liquid.

Process of separation of ethanol and water is as follows:
i. Mixture of ethanol and water is heated in the round bottom flask.
ii. As the mixture begins to heat, vapours of the ethanol will be formed as it has low boiling point.
iii. Along with ethanol, some of the vapours of water will also be formed as they have less difference in their boiling points.
iv. Both the vapours will try to rise up through the fractionating column but the vapours of water will condense while passing through the fractionating column and condense back to the round bottom flask and vapours of ethanol will rise to the top of the column and will pass through the condenser and received in the flask.
v. Ethanol is collected in the beaker first and water is left behind and the mixture is separated.

Subject: Biology
Topic: Sense Organs

Questions:
Spectacles with convex lenses correct long sightedness by ______ (WASSCE 2009)

A. converging the light rays before they enter the eye
B. diverging the light rays before they enter the eye
C. reducing light intensity before it enters the eye
D. Increasing light intensity before it enters the eye


Answer is A

Explanations:
Converging lenses converge light rays so that they are brought to a focus on the retina. The more long sighted a person is, the more convex the lens has to be to correct the vision deficiency by bringing the rays of light into focus. A long sighted person's focus is actually some way behind the back of the eye and the convex lens pulls the rays of light together sooner than they normally would be.

Subject: Physics
Topic: Simple Harmonic Motion

Questions:
Which of the following statements about the motion of a simple pendulum is true? (WASSCE 2020)

A. It is a simple harmonic motion when the angle of displacement is large.
B. It passes the equilibrium position with minimum speed.
C. It possesses maximum kinetic energy at the extreme positions.
D. It swings faster at the poles than at the equator.

Answer is D

Explanations:
The characteristics of Simple Harmonic Motion (SHM) are as follows:
1. It is a simple harmonic motion when the angle of displacement is small.
2. It passes the equilibrium position with maximum speed and with minimum speed at the extreme positions of oscillation.
3. It possesses maximum kinetic energy and minimum P.E at the centre and maximum P.E. and minimum K.E. at the extreme positions.
4. It swings faster at the poles than at the equator (equilibrium position).
5. The acceleration of the body is always directed towards a fixed point (i.e. at the centre). The magnitude of this acceleration is directly proportional to the displacement.

Subject: Economics
Topic: Theory of Production

Question:
If all factors are variable in the long run, firms will experience _____ (JAMB 2012)

A. decreasing returns to scale
B. increasing returns to scale
C. diminishing returns
D. economies of scale

Answer is D

Explanations:
Economies of scale is a cost saving advantage that accrues to a firm as a result of producing or operating on a large scale. Economies of scale are cost advantages reaped by companies when production becomes efficient.

If firms vary all inputs in the long run, the firm will experience economies of scale since all inputs will be variable, thus, costs are spread on all inputs.
