Example: 1. A heating coil is immersed in a 100. g sample of liquid water which boils at 99.61°C in an open
insulated beaker on a laboratory bench at 1.0 x 10^5 Nm-2 pressure. In this process, 10 % of the liquid is
converted to the gaseous form at a pressure of 1.0 x 10 ^5Nm-2. A current of 2.00 A flows through the heater
from a 12.0 V battery for 1 x 10s to effect the transformation. The densities of liquid and gaseous
water under these conditions are 997 and 0.590 kg m-3, respectively. Calculate q and w for the process

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.)
