One day you look in your refrigerator and find nothing but a dozen eggs (44 g each). A quick measurement shows that the inside of the refrigerator is 1.0 m by 0.60 m by 0.75 m. Is the weight of the air in the refrigerator (a) much less than, (b) about the same as, or (c) much more than the weight of the eggs?
Solution:
(b) The air and the eggs weigh about the same.
States of Matter:
Solid: maintains its shape and volume.
Crystalline: orderly, three-dimensional pattern that repeats. (metals, salt)
Amorphous: not arranged in any orderly and repetitive array. (rubber, resin, plastic)
Quasi-crystalline: orderly, three-dimensional pattern that does not repeat itself.
Composite: composed of several different materials. (wood, bone)
Liquid: a transition state between solids and gases.
Viscosity is the internal resistance of an object moving through a liquid.
We will an ideal liquid that is incompressible and nonvicous.
