Physical Properties of Matter Flashcards
True or False.
The arrangement of atoms determines the properties of different types of matter.
True
True or False.
When substances mix together and form mixtures, the properties of the substances that make up the mixtures are not present anymore.
False
Define physical property.
A physical property is a characteristic of matter that you can observe or measure without changing the identity of the matter.
How do aluminum, water, and air differ?
Aluminum is an element, water is a compound, and air is a mixture.
What are the states of matter?
solids, liquids, and gas
True or False.
The state of matter is a physical property of matter.
True.
What makes some matter a solid and other matter a liquid, or a gas?
It depends on how close the particles in the matter are to one another and how fast they move.
Which state of matter flows, keeps the same volume, and takes the shape of its container?
Liquid. It is because the particles that make up a liquid have more energy and thus more motion than the particles in a solid. Each particle still touches the particles around it, but the particles slide past each other.
What are properties that are size-dependent?
mass, conductivity, volume
What are properties that are size-independent?
boiling/melting points, state of matter, density, solubility, magnetism
Why is mass a size-dependent property of a given substance?
It is because its value depends on the size of a sample.
What is the difference between mass and weight? Give an example.
Mass is an amount of matter in something while weight is the pull of gravity on that matter. Weight changes with location, but mass doesn’t. If a person was on the moon, the person would have the same mass that it has one earth but the weight would be less on the moon because its gravity pull is less compared to earth.
What is volume?
Volume is the amount of space something takes up.
What is the most common unit of measurement for volume?
milliliter (mL)
What is the degree of temperature for melting point?
0 degrees
What is the degree of temperature for boiling point?
The boiling point of water is 100 degrees at sea level.
True or False.
The temperature does depend on how much water is in the container.
False.
What is density?
Density is the mass per unit volume of a substance. It is the measure of how compact the mass in a substance or object is.
Formula for density?
d= mass/volume
A sample of wood has a mass of 12g and a volume of 16mL. What is the density of the wood?
0.75 g/mL
What are the 2 types of conductivity?
Electrical conductivity and thermal conductivity
Define solubility.
Solubility is the ability of one substance to dissolve in another.
Define conductivity.
Conductivity is the ability of matter to conduct, or carry along, electricity or heat.
How do you use volume to separate mixtures?
Volume could be used to separate mixtures whose parts can be separated by filtration.
