Document Summary
The average of the kinetic energy of a substance (molecular motion) measured with a thermistor or thermometer and measured in units of degrees. Kelvin (k)- absolute scale based on theory of absolute zero (all molecular motion seizes) 100 degrees between melt/freeze point and boil/steam point. Celsius (c)- starts at absolute zero: no negative values. Known as the centigrade scale- 100 units between freeze and boil. 1 unit is the same as kelvin but different starting points. **know the freeze and melt points in all scales. Maximum thermometer- mercury (measure the hottest part of day) Minimum thermometer- alcohol (measure coldest temperature of the day) Diurnal temperature variance (range): difference between daily maximum and daily minimum temperature. High diurnal temp: biggest difference between this high temp and low temp. Latitude: insolation is most important influence on temperature and variations. Altitude: temperature decreases with increasing altitude in the troposphere.
