On a new scale of temperature (which is linear), an called the W scale, the freezing and boiling point of water are 39^o W and 239^o W respectively. what will be the temperature of 39^o C celsius scale?

78^o W

117^o C

200^o C

139^o W

Solution

117^o C

In general, whenever we are to go from any known scale to any unknown scale, then we follow the equation
(temperature on known scale) - (LFP for known scale)
______________________________________________
(UFP - LFP ) Known (temerature on unknown scale)
= - (LEP for unknown scale)
________________________________________
(UFP-LFP) unknown
or $fraction numerator 390 minus 0 over denominator 100 minus 0 end fraction space equals space fraction numerator t minus 39 over denominator 239 minus 39 end fraction$
t= 117^o W
LFP = Lower fixed point
UFP = Upper fixed point
