Answers to Section B (Essay) Questions of Junior WAEC 2025 Basic Technology
Question 1
(a) What is food storage?
Food storage is the process of keeping food in a safe place or condition to prevent spoilage and maintain its quality for future use.
(b) State three (3) various food storage methods you know.
1. Storing in a refrigerator or freezer
2. Keeping in a dry, cool cupboard or pantry
3. Sealing in airtight containers
(c) (i) Name three (3) various food preservation techniques:
1. Salting
2. Canning
3. Smoking
(ii) Give an example of food that is preserved by each technique:
1. Salting – Fish
2. Canning – Tomatoes
3. Smoking – Meat
Question 2
(a) What is work done?
Work done is the amount of energy transferred when a force is applied to an object and the object moves in the direction of the force.
Formula: Work Done = Force × Distance
(b) If a force of 10 Newtons moves a load through a distance of 24 meters. Calculate the work done.
Work Done = 10 N × 24 m = 240 Joules
Question 3
(a) Mention four (4) operating gases that could be used in a refrigerator, freezer and air conditioner:
1. Ammonia (NH₃)
2. Freon (R-12)
3. R-134a
4. R-22
(b) What is the use of a thermostat in a refrigerator?
A thermostat regulates the temperature inside the refrigerator by turning the cooling system on or off to maintain a desired temperature.
(c) Define (explain) the following terms in technical drawing:
(i) Oblique:
A type of pictorial drawing where the front face is drawn in true shape and size, while the sides are drawn at an angle (usually 45°) to give a 3D view.
(ii) Pictorial drawing:
A drawing that shows the height, width, and depth of an object in a single view to make it look more realistic.
(iii) Projection line:
Lines used in technical drawings to transfer dimensions or features from one view to another.
(iv) Outline:
The visible edge or boundary of an object drawn with thick continuous lines.
(v) Axis:
An imaginary central line around which an object rotates or is symmetrically arranged.
(d) Why is ammonia gas used mostly in the refrigerator?
Ammonia is used because it absorbs heat quickly, has a high cooling effect, and is efficient for heat transfer in refrigeration systems.
Question 4
A transformer has 400 volts as output voltage, if the primary and secondary windings are 40 and 50 turns respectively:
(i) What type of transformer is it?
It is a step-up transformer (because the number of turns in the secondary coil is more than the primary).
(ii) Calculate the input voltage.
Using the transformer formula:
Vp/Vs = Np/Ns
Where:
Vp = input voltage (primary),
Vs=400V,
Np=40,
Ns=50
Answer: Input voltage = 320 volts
