En un recipiente de masa despreciable, se agrega 0.140 kg de hielo a -15.0°C a 0.190 kg de agua a 35.0°C. a) Si no se pierde calor al entorno, ¿qué temperatura final alcanza el sistema? b) A la temperatura final, ¿cuántos kilogramos hay de hielo y cuántos de agua líquida?

On a day when the barometer reads 75.23 cm, a reaction vessel holds 250 ml of ideal gas at 20 celsius. an oil manometer ( ρ= 810 kg/m^3) reads the pressure in the vessel to be 41 cm of oil and below atmospheric pressure. what volume will the gas occupy under s.t.p.?

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 1.90
