12. Consider the statement "Two samples that have the
same mass, volume, density, and boiling point are
composed of the same substance, even if the two sam-
ples have different melting points." Which of Stu-
dents 2 and 4, if either, would be likely to agree with
this statement?
F. Student 2 only
G. Student 4 only
H. Both Student 2 and Student
J. Neither Student 2 nor Student 4
3. Suppose that the temperature of Sample D is increased
to 890°C at 1 atm of pressure. Will the sample's den-
sity be lower than or higher than it was at 20°C and
1 atm ?
A. Lower; Sample D will be a gas, and gases gener-
ally have lower densities than do solids.
B. Lower; Sample D will be a liquid, and liquids gen-
· erally have lower densities than do solids.
C. Higher; Sample D will be a gas, and gases gener-
ally have higher densities than do solids.
D. Higher; Sample D will be a liquid, and liquids
generally have higher densities than do solids.
