What should you do if you spill a liquid on electrical equipment?
Unplug the equipment and allow it to dry completely.
Wipe the liquid with a dry cloth and plug it back in immediately.
Pour more liquid to dilute the spill and clean it up.
Ignore the spill and continue using the equipment.
List two properties of wood that make it a useful material.
Poor aesthetic appeal
Strength and durability, good insulation properties
Lightweight and fragile
Highly flammable
What is the difference between hardwood and softwood?
Hardwood is softer than softwood.
Hardwood is used exclusively for furniture.
Softwood comes from broadleaf trees.
Hardwood is from deciduous trees; softwood is from coniferous trees.
How does moisture affect the properties of wood?
Moisture has no effect on the color of wood.
Moisture causes wood to expand or contract, affecting its strength, durability, and structural integrity.
Moisture makes wood lighter and easier to handle.
Moisture increases the electrical conductivity of wood.
What are some common uses of metals in construction?

Poor resistance to chemicals
The advantages of using rubber in products include elasticity, durability, excellent grip, cushioning, waterproof properties, and temperature resistance.
How do the properties of materials influence their use in technology?
The properties of materials influence their use in technology by determining their suitability for specific applications based on characteristics like strength, conductivity, and weight.
All materials are equally suitable for any technology regardless of their properties.
The properties of materials have no impact on their technological applications.
Materials are chosen based on their color and texture alone.
