AIPMT MAIN 2008 Physics Temperature Scales MCQ Question
Type: MCQ-numerical-Medium-Class 11
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° C on the Celsius scale?
A
139° W
B
78° W
C
117° W
D
200° W
Correct Answer
Option C
Detailed Explanation
Using the linear relationship between the scales: (39 - 0)/(100 - 0) = (x - 39)/(239 - 39), solving gives x = 117° W.
