[WWatsford]

A spherical object 25.0 cm in diameter having an emissivity of 0.800 is held at a temperature of 275C by an internal heater.
 
  This object is embedded in a very large vat of water at 100.0C and atmospheric pressure. At what maximum rate (in g/min) is the water evaporating in the vat due to the radiated heat it receives from the object? You can ignore any heat radiated by the water. The latent heat of fusion for water is 33,400 J/kg, its latent heat of vaporization is 2.26  106 J/kg, and the Stefan-Boltzmann constant is 5.670  10-8 W/m2  K4.

Question 2

  A) 10
  B) 14
  C) 18
  D) 22
