Temperature (dry adiabatic lapse rate) changes at about 2 per degree F per 1000 ft, dew point more slowly (saturated adiabatic lapse rate), at about 3 degree F per 1000 ft. See http://en.wikipedia.org/wiki/Adiabatic_lapse_rate. jb
You measure humidity with a psychrometer. It is a tool that has 2 thermometers connected to either side of a piece of material. One of the thermometers is normal and the other one has a wet sock on it. To use the psychrometer you spin it for 2 minutes or so and you take the temperature on the dry bulb thermometer (the normal one) and take the temperature of the wet bulb thermometer (the one with the wet sock on it). The wet one will dry out more if there is less moisture in the air because as you are spinning it you are evaporating the water into the air. The dryer air can hold more water than moist or humid air. By comparing the two numbers you can figure out the wet bulb depression, the dewpoint, and the relative humidity.
Room temperature
The time it takes for 2 gallons of water to reach room temperature will depend on the initial temperature of the water, the room temperature, and the surrounding conditions. In a typical room environment, it may take a few hours for 2 gallons of water to reach room temperature if starting from a colder temperature.

what is 2+2
After dropping 10 degrees from 8 degrees, the temperature would be -2 degrees.
The temperature had risen from -2 degrees Fahrenheit in the morning to a warmer temperature by noon. The exact number of degrees it had risen would depend on the new temperature at noon.
-19° C (-2° is the average temperature
No, "minus 2 degrees" and "2 degrees below zero" refer to the same temperature. Both expressions indicate a temperature of -2 degrees. Therefore, there is no difference in temperature between the two descriptions; they are equivalent.
5 degrees below 2 Celsius is -3 Celsius.
2/13/2011 Temperature is 49F.
the temperature was -2 degrees Fahrenheit
The average temperature is 2 degrees Celsius.
