whitney: Cher, I would like to check, abt how many Six's thermometer are suppose to have in a stevenson Screen? 5 Aug 13, 08:34 PM whitney: plus the metal indices 5 Aug 13, 08:32 PM whitney: cher, the slide 7, how does the thermometer work, with mercury and alcohol(as in how does it work)??
MISS ST: There is no fixed number of thermometers to be placed inside. It depends on how big the screen is, and how many you want to put inside. The mercury-in-glass thermometer consists of a bulb containing mercury attached to a glass tube. The volume of mercury in the tube is much less than the volume in the bulb. The volume of mercury changes slightly with temperature; the small change in volume drives the narrow mercury column up the tube.

MISS ST: Atmoshpere is the layer of gases that surrounds the Earth eg Oxygen.
