What state of matter has a changeable shape, low compressibility, and fixed volume.
liquid
Compare crystalline and amorphous solids
Crystalline - solids with particles arranged in regular repeating patterns, or lattices; Amorphous - solids that consist of a mass of particles with no discernible pattern.
What factor determine the state of a substance.
Kinetic energy and bonded forces
What is the most common state of matter?
Plasma
Compare the degree of motion of the particles in solids, liquids, and gases.
Solids-Closely spaced,held in place, moved by vibration Liquids-Closely spaced vibrate&slide Gas-Widely Spaced,Move freely&Rapidly
What is viscosity
a measure of a fluid's resistance to flow
What is plasma?
an ionized gas. consist of positive electrons.
Why can one substance be a gas, and another be solid at the same time?
attraction rate at the same temp.
Describe a solid
not a movable shape and fixed volume
List the 4 most common states of matter.
plasma, solid, liquid, gas
How would increasing the temp. affect the viscosity of a liquid?
resistance would go down.
What state of matter has a fixed shape and volume?
solid
What property allows you to describe liquids and gasses as fluids.
they aren't rigidly held together
