DIVERSITY: Exploring Matter by its Physical Properties Quiz

What are some common physical properties of matter?

• Strength, Hardness, Density, Melting point

• Color, Taste, Smell, Sound

• Magnetism, Radioactivity, Transparency, Viscosity

• Electrical conductivity, Thermal conductivity, Boiling point, Flexibility

How do we investigate the density of objects?

• Estimate length, mass and volume

• Use a thermometer to measure temperature

• Observe the transparency and reflectivity

• Measure the color, taste and smell

What are the effects of different densities?

• Objects will sink if their density is higher than the medium, and float if lower

• Density has no effect on whether objects sink or float

• Objects will always float if their density is low

• Objects will always sink if their density is high

How can understanding the physical properties of materials affect our choices for sustainable living?

• It leads to using more non-sustainable materials

• It only affects the cost of materials

• It helps in making informed choices and considering environmental impact

• It has no impact on sustainable living

Why is it important to know the physical properties of matter?

• To win a science competition

• To make informed choices for household products

• To impress friends with scientific knowledge

• To confuse people with complex terms

How do mass and volume affect the density of an object?

• Higher mass and volume lead to higher density

• Lower mass and volume lead to higher density

• They have no effect on density

• Higher mass and volume lead to lower density

What is the formula to calculate density?

• Density = Mass x Volume

• Density = Mass + Volume

• Density = Mass - Volume

• Density = Mass / Volume

How can we design and construct an effective water purification device?

• By considering the effects of different densities

• By using alternative materials with similar properties

• By applying the 3Rs (reduce, reuse, recycle)

• By using only natural resources

What happens to an object if its density is higher than the surrounding medium?

• It will disappear

• It will float

• It will explode

• It will sink

How may we obtain cleaner water?

• By designing and constructing a water purification device

• By calculating the density of water

• By increasing the pollution levels

• By ignoring the physical properties of materials
