Relative Humidity in the Winter and Summer
This applet simulates what happens inside a house when the temperature and dew point change outside. The user of this applet has control over the outdoor values of the two thermometers (one for temperature and one for dew point). The relative humidity meter will instantly display the value for the outside. The user will learn that as the outdoor values are changed, the indoor environment is slower to change; and if the air is colder outside, the furnace will cycle on and off, keeping the house at approximately the value the thermostat was set to. The impact of activities on the indoor environment can also be observed.
