Phases of Matter
What phase of matter is the typical rock that is found outside?
Solid.
Is mass an intensive or extensive property?
Extensive.
What is the formula for density?
Density = mass/ volume
What are the four phases of matter?
Solid, liquid, gas, and plasma.
What are intensive properties good for?
Identifying materials.
m = 20 kg
V = 5 m^3
What is the density?
4 kg/m^3
Which phase of matter possesses subatomic particles in mixture?
Plasma
Define an intensive property.
A physical property that does not depend on the amount of material.
What is the formula for mass?
Density times volume.
Solid, liquid, gas, and plasma.
Which of these are extensive properties?
Mass, volume, density, solubility, length, weight, heat capacity.
Mass, volume, length, weight, heat capacity.
What is the formula for volume?
mass / density
Which of these is an example of a material that typically behaves as both a solid and a liquid?
Shaving cream, oobleck, aluminum bar, air?
Oobleck
Which of these is an intensive property?
Height, volume, weight, density, mass, length, width, boiling point.
Density and boiling point.
Material A:
density A = 800 kg/m^3
volume A = 40 m^3
Material B:
density B = 400 kg/m^3
volume B = 100 m^3
Material A and B form a mixture. What is the mass of the mixture?
72,000 kg
mass of A + mass of B = mass of mixture
density of A * volume of A + density of B * volume of B = mass of mixture
