Оп 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^ C on the Celsius scale?
Options
- A78^ W
- B117^ W
- C200^ W
- D139^ W
Correct answer
B. 117^ W
Step-by-step solution
Given, ( aligned & T _ f =39^ W & T _ b =230^ W aligned ) We know that, ( aligned & T _ b - T _ f 100^ C - o ^ C = T -39^ C 39^ C & 239-39 100 = T -39 39 & 200 100 = T -39 39 & ~T -39=2 39=78^ W & T =39+78=117^ W aligned )
