An open pot of water is heated on the stove top. Which of the following statements best describes the temperature of the water?
A) The temperature of the water will continually increase as heat from the burner is applied.
B) The temperature of the water will increase until the water becomes a superheated vapor.
C) The temperature of the water will increase until the water becomes a compressed liquid.
The temperature of the water will increase only to the saturation temperature.
4. Relative Humidity calculations (use the Water vapor Pressures and Contents scale)!
The actual water content (absolute humidity) of a sample of room air is measured and is
°C, what is the relative
found to be
If the room temperature is
humidity?
Use examples below to fill in the blanks above:
a. Absolute humidity is 11.91 mg/L; Temperature is at 24 °C
b. Absolute humidity is 13.89 mg/L; Temperature is at 30°C
c. Absolute humidity is 10.01 mg/L; Temperature is at 60 °F

9. If machine parts are degreased by means of kerosene as shown in the diagram,
how much kerosene make-up is needed per day? How much kerosene has to enter
the degreasing vat per day? There are about 3 lb of grease per 100 lb of machine
parts, and 60 tons of machine parts are processed each day. Five thousand pounds
of kerosene (the 10% solution) are carried away by the machine parts each day
but drip off and are caught and put back in the degreasing vat. Two hundred
pounds of the 10% solution are lost each day from the vat by evaporation, spillage,
or by being carried away.
