PHYSICS HELP (a) A typical steam jet shoots 3.62 kg of 157°C water vapor onto an intruder. How much energy is released by the cooling of the water vapor from 157°C down to the point where it can condense, 100°C? Specific heat of water vapor is 2020J/kg°C

(b) Once cooled how much heat is released by the condensation of the water vapor? The Latent Heat of Vaporization is 2,260,000 J/kg

(c) Now that the water is in liquid form, find how much more heat is released by the water as it cool to skin temperature of 26°C, then add the other energy to find the total heat released during the entire ordeal.

speed of light in vacuum is 300,000 km/s

speed of light in other mediums is given by the expression v = c/n, where c is the speed of light in vacuum and n is the refractive index of medium.

for the first medium v = 200,000 km/s

  so, refractive index of medium = 300000/200000 = 1.5

    1.5 refractive index is usually for glass. so first medium is glass.

for the second medium v = 250,00 km/s

so, refractive index of medium = 300000/250000 = 1.2

    1.2 refractive index is usually for water. so second medium is water.

for the third medium v = 0 km/s

so, refractive index of medium = 300000/0 = ∞

    ∞ refractive index is usually for opaque mediums. so third medium is opaque medium.
