Tome saturated water vapor is contained in a high-pressure vessel at 600 kPa and 158.83 oC. The vapor is heated at constant pressure until the temperature reaches 300 oC. The mass of the vapor is 7 kg. Find the initial and final volumes V1 and V2 in m3. Find the boundary work done during the process in kJ.

The initial and final volume are: 2.33 m³ and 3.09 m³

The boundary work is 456 kJ

what is the speed of a softball that travels 20m in 2secs

speed = 20/2 = 10 m/s

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.
