On a new linear scale of temperature (called W scale) the freezing and boiling points of water are 35°W and 235°W respectively. The temperature on the new scale, corresponding to 70°C temperature on celsius scale, will be
Options
- A210^ , W
- B175^ , W
- C105^ , W
- D70^ , W
Correct answer
B. 175^ , W
Step-by-step solution
The relationship between any two linear temperature scales is given by: W - W_ FP W_ BP - W_ FP = C - C_ FP C_ BP - C_ FP Since the liquid is water, the freezing and boiling points on the Celsius scale are 0^ C and 100^ C respectively. Substituting the given values: W - 35 235 - 35 = C - 0 100 - 0 W - 35 200 = C 100 W - 35 = 2C For C = 70^ C : W - 35 = 2 70 W - 35 = 140 W = 175^ W Answer: 175^ , W
