Organic materials (such as food scraps and yard waste) in landfills can decompose and produce landfill gas ( LFG ) over time. About 50% of LFG is methane, a greenhouse gas with a global warming potential 25 times higher than that of carbon dioxide over a 100 -year period. LFG can be collected and burned to produce electricity. i. Explain a process during which LFG is burned to produce electricity

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.
