Exam 10: Matter, Light, and Glass Examination

When a substance undergoes a change of state from liquid to gas, the attractive forces between the molecules increase in strength.

If glass cannot be physically pieced together, then the control and question glass are best compared by their refractive index and ________.

Crystalline solids, with the exception of ________ crystals, exhibit ________, or the property of refracting a beam of light into two different ray components.

Match the word in Column 1 to its definition in Column 2. Each answer can only be used once. A)The separation of light into its component wavelengths B)A constant property of matter that reflects the amount of material present C)The behavior of a substance without alteration of the substance's composition through a chemical reaction D)A difference in the two indices of a refraction exhibited by most crystalline materials E)The bending of a light wave as it passes from one medium to another F)A property of matter that depends on both the mass of a substance and the effects of gravity on the mass G)A physical property of matter that is equivalent to the mass per unit volume of a substance H)Glass that is strengthened by introducing stress through rapid heating and cooling of the glass surfaces I)A crack in a glass that forms a rough circle around the point of impact J)A crack in a glass that extends outward like the spoke of a wheel from the point at which the glass was struck K)The behavior of a substance when it reacts or combines with another substance L)A property that is not dependent on the size of the object M)A bright halo that is observed near the border of a particle immersed in a liquid of a different refractive index N)Two sheets of ordinary glass bonded together with a plastic film -Dispersion
