113. Read the passage about a science experiment
that Jacob conducted
Jacob took an empty water bottle and put the
lid on it. He then put the water bottle into a
boiling water bath After 5 minutes, Jacob
removed the bottle and immediately placed it
in a cold water bath.
Which of the following best explains what Jacob
observed?
The water bottle collapsed because the volume
"increased as the temperature decreased.
B. The water bottle collapsed because the volume
decreased as the temperature decreased.
The water bottle expanded because the volume
increased as the temperature decreased.
D. The water bottle expanded because the volume
decreased as the temperature decreased.

People with normal vision cannot focus their eyes underwater if they aren't wearing a face mask or goggles and there is water in contact with their eyes. in a simplified model of the human eye, the aqueous and vitreous humors and the lens all have a refractive index of 1.40, and all the refraction occurs at the cornea, whose vertex is 2.60 cm from the retina. with the simplified model of the eye, what corrective lens (specified by focal length as measured in air) would be needed to enable a person underwater to focus an infinitely distant object? (be careful-the focal length of a lens underwater is not the same as in air! assume that the corrective lens has a refractive index of 1.62 and that the lens is used in eyeglasses, not goggles, so there is water on both sides of the lens. assume that the eyeglasses are 2.05cm in front of the eye.)
