Water in a 5-cm-deep pan is observed to boil at 98°C. At what temperature will the water in a 40-cm-deep pan boil? Assume both pans are full of water.

Refrigeration tubing is 2 inches in diameter and 10 ft. long and contains R 12 as a saturated vapor at o°F. What is the mass of R 12 in the tubing?

Water is to be boiled at sea level in a 30-cm-diameter stainless steel pan placed on top of a 3-kW electric burner.If 51 percent of the heat generated by the burner is transferred to the water during boiling, determine the rate of evaporation of water. Please give your answer in kg/hour.

the latent heat of vaporization is about 2.44 x 10⁶ J/kg and the density (density) of the vapor is 0.598 kg/m³ at 100 °C per km.  Determine the rate of change of the boiling point with altitude approaching sea level in °C per km.  It is known that the density of air at 0°C and 1 atm is 1.29 kg/m and the density of water is 1000 kg/m³.  Assume the air temperature is 300°K.  The change in pressure with altitude is given by the relationship P(z) = P(0)exp - (mgz)/(kT)
