Select any four of the physical properites listed in Table 1.1 on page 22 and use them to describe: gold, sugar, water.
I don't quite understand what this question is asking. Maybe you could give an example?
Here is the table of physical properties as mentioned.
State - solid, liquid, gas
Colour - colour
Malleability - Ability to be beaten into sheets
Ductility - Ability to be drawn into wires
Crystallinity - Shape or appearance of crystals
Magnetism - Tendency to be attraced to a magnet
Solubility - Ability to dissolve in water
Conductivity - Ability to conduct electricity or heat
Viscosity - Resistance to flow
Density - Ratio of a material's mass to its volume
Meltiing/freezing point - Temperature of melting/freezing
Boiling/condensing point - Temperature of boiling/condensing
Thanks.
I'm not positive what the question is asking either, but here goes.
Choose sugar.
State: sugar is a solid.
color: white
solubility in water: yes.
ductility: not ductile
malleability: not malleable.
magnetism: not magnetic
but you only require four of them.
To use the physical properties listed in Table 1.1 to describe gold, sugar, and water, we need to select four properties for each substance.
Gold:
1. State: Solid
Gold is naturally found in a solid state. It does not easily change its shape or volume under normal conditions.
2. Colour: Gold
Gold has a distinct yellowish color. This unique color is the reason for its popularity in decorative and ornamental purposes.
3. Malleability: Highly Malleable
Gold is one of the most malleable metals. It can be beaten into extremely thin sheets, even to the point where it becomes translucent.
4. Density: High Density
Gold is a dense material. It has a high ratio of mass to volume, which means a relatively small piece of gold can have a significant amount of weight.
Sugar:
1. State: Solid
Sugar is typically found and used in its solid form, such as granulated, powdered, or crystallized sugar.
2. Colour: White (in its refined form)
Refined sugar, commonly used in households, is a crystalline substance that is generally white in color.
3. Solubility: Highly Soluble in Water
Sugar can dissolve easily in water. When added to a liquid, it dissolves quickly, forming a sweet solution.
4. Crystallinity: Crystalline Structure
Sugar has a crystalline appearance, which can be observed under a microscope. This structure affects its texture and behavior when heated or cooled.
Water:
1. State: Liquid
Water is commonly found and used in its liquid state, making it essential for life on Earth. It can also exist as a solid (ice) and a gas (water vapor).
2. Colour: Colorless
Pure water is colorless, although it can appear blue when seen in large quantities due to light reflection.
3. Boiling/Condensing Point: 100°C (boiling), 0°C (condensing)
At sea level, water boils at 100°C and condenses at 0°C. These temperatures mark the transition between liquid and gaseous states of water.
4. Density: Maximum Density at 4°C
Water has a unique property where its density is highest at 4°C. As the temperature increases or decreases from this point, the density of water decreases, which is why ice floats in liquid water.
To find these physical properties for different substances, you can refer to scientific literature, textbooks, or reliable online sources that provide information about the specific substance you are interested in.
