Astudent freezes water in one ice cube tray and olive oil in another. the student finds that the ice cube in the liquid water while the olive oil sinks to the bottom.

a) compare the density’s of the 2 liquids

b) compare the two solids and liquids terms of the differences in the spaces between their particle.

c) most liquids behave like the olive oil when frozen. however, it’s fortunate for life on earth that water is an exception. suggest one reason why.

d) list at least two science-related questions that you have based on this information.

e) choose one question from part d) and describe how you would investigate to find the answer.

The last few miles of the marathon are the most difficult for heather, her hair plastered to her head, sweat clinging to her arms, and her legs already feeling as if they had nothing left, just dead weight. after grabbing a cup of ice water, she feels the ice cubes smash against her nose as she gulps some cool refreshment and keeps on running. in these last few miles, the breeze kicks up and she finally feels some coolness against her skin. drips of sweat, once clinging to her forehead, now spill down, and heather feels more pain as the sweat flows into her eyes.which of the following is the most likely reason why the ice struck heather’s nose when she took a drink? a) water can function as a solvent. b) water can store large amounts of heat. c) water can moderate temperatures through evaporative cooling. d) the density of water decreases when it freezes. e) water has a cohesive nature.sweat remained on heather’s forehead and arms because of the a) high salt content of sweat b) cohesive nature of water c) ability of water to moderate heat d) high evaporative cooling effect of water e) ability of water to act as a solvent

The atom fluorine generally will become stable through the formation of an ionic chemical compound by accepting electron(s) from another atom. this process will fill its outer energy level of electrons.
