A nonburning helium core surrounded by a shell of hydrogen-burning gas characterizes the subgiant stage of stellar evolution. As time goes on, the star continues to evolve, and eventually, it becomes a red giant. Rank the stages a star goes through as it evolves from a subgiant into a red giant, from latest to earliest. Rank the stages a star goes through as it evolves from a subgiant into a red giant, from latest to earliest. a. The shell of hydrogen surrounding the star's nonburning helium core ignites. b. Pressure in the star's core decreases. c. Pressure from the star's hydrogen-burning shell causes the nonburning envelope to expand. d. The star's nonburning helium core starts to contract and heat up. e. The star becomes a red giant. f. The surface of the star becomes brighter and cooler.

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.
