Question 388: Properties of Matter

Question

On a new scale of temperature (which is linear) and called the W scale, the freezing and boiling points of water are 39

W and 239

W respectively.  What will be the temperature on the new scale, corresponding to a temperature of 39
o
C on the Celsius scale ?

Accepted Answer

W is the temperature on new scale corresponding to 39ÃÂºC on ÃÂºC scale.
So, (C Ã¢ÂÂ  0)/(100 Ã¢ÂÂ 0) = (W Ã¢ÂÂ 39)/(239 Ã¢ÂÂ 39)
$$ \Rightarrow $$ C/100 = (W Ã¢ÂÂ 39)/200
$$ \Rightarrow $$ W = (C/100) ÃÂ 200 + 39
= (39/100) ÃÂ 200 + 39
= 78 + 39 = 117
So, temperature on new scale is 117ÃÂ°W corresponding to 39ÃÂ°C.
