On a particular summer day, the temperature is 30 degrees Celsius and the relative humidity is 80% (which means that the partial pressure of water vapor in the ambient air is 80% of the equilibrium vapor pressure of water). A sample of this air is placed in a 1 Liter flask which is then closed and cooled to 5 degrees Celsius. What is the mass in grams of water that still exists as vapor in the flask? How much liquid...

The indoor temperature of an oven can go up to 250 degrees Celsius. There is a 2 mm thick sheet metal material inside and outside of the oven wall. There is a 10 mm insulation material between the oven wall. It is desirable that this temperature should not exceed 30 degrees Celsius in order not to damage the outside of the oven by hand. Find the amount of heat (W) discharged from the furnace unit area and unit time and...
