Note that the density of mercury is
(i) 13545 kg/m^3 at 20 deg.C
(ii) 13472 kg/m^3 at 50 deg, C
For a given mass, M kg, by using the volume at 20 deg. C, obtain
M = (13545 kg/m^3)*(0.002 m^3) = 27.09 kg .
Let V m^3 = volume at 50 deg. C
Then
(13472 kg/m^3)*(V m^3) = 27.09 kg
V = 27.09/13472 = 0.002010837 m^3
Answer:
The closest answer is A. 0.002010812 m^3
Why do elliptical galaxies appear yellow or red?
A) a. They have very little dust or cool gas, and thus have little ongoing star formation
B) b. They contain only massive-stars that have progressed to the red-giant stage C) c. They contain no hot, young blue stars
D) a and c
E) a and c
E
Answer:
Ionic bonding.
Explanation:
According to our crude, conceptual definition, chemical bonds can form either by electron transfer between atoms or by sharing of electrons. ... When atoms lose or gain electrons, they become what are called ions. Loss of electrons leaves an atom with a net positive charge, and the atom is called a cation.
