13) Metals are both good heat conductors and good electrical conductors because of the
a) Similarity between thermal and electrical conductive properties.
b) Looseness of outer electrons in metal atoms.
c) Relatively high densities of metals.
d) High elasticity of metals.
e) Ability of metals to transfer energy easily.
Explanation:
54) A factor that usually determines whether a substance is in the sold, liquid, gaseous, or plasma state is its
a) Pressure
b) Volume
c) Temperature
d) A and C
e) A, B and C
Explanation:
63) Some molecules are able to absorb large amounts of energy in the form of internal vibrations and rotations. Materials composed of such molecules have
a) High specific heats.
b) Low specific heats.
c) None of the above.
Explanation:
i need not only the answer but a brief explanation of why the answer is correct. i am doing test corrections from previous tests so that i can do well on the midterm in a week. thanks!
