comment the temperature exercises we did in first yesr physics legend "THEMISTER AND THERMOCOUPLE TEMPERATURE" key at 2 "VERSUS MERCURY STANDARD TEMPERATURE" xaxis "MERCURY TEMP (kelvin)" yaxis "THERMOCOUPLE TEMPERATURE" mark x=350 y= 350 line = shortlong plot "THERMISTER" line = nil regression point = circ data "data6" plot "THERMOCOUPLE" regression 4 line = short point = cross data "data7"
