				(°C)	Kelvin (K)
R1	174	175	174 - 176	175	448.15
R2	174	176		176	449.15

Mean			-	175.33	448.48
Standard Deviation				0.58	0.58
Boiling Point [in Kelvin (K)]    = Observed Boiling Point(°C) + 273.15                                                          = 175 + 273.15                                                          = 448.15
