Which is true of saturn's satellite, titan?
o
a. it is about half the size of the planet it orbits.
o
b. it is saturn's only satellite.
c. its surface temperature is much warmer than the surface
temperature of earth.
d
d. it may be similar to earth's early conditions.

D. It may be similar to Earth's early conditions.

Explanation:

Titan is one of the many satellites orbiting planet saturn. This satellite is very interesting as it shows a lot of similarities with the conditions at play when the early earth formed.

The early earth atmosphere was made up of reduced gases lacking in oxygen. Titan's atmosphere also share this similarity. It's atmosphere is predominantly made up of nitrogen, methane and carbon dioxide.

Titan also has a rocky surface just like earth and it has an atmospheric cover.

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
