Question:
A scientist uses a scale y for measuring temperature .in this scale,pure water melts at 10 degree y and boils at 130 degree y .the scientist measured the temperature at which sodium melt to be 127 degree y.express this temperature in kelvin
Answer:
No. of divisions in the Y-scale = 130 – 10 = 120 divisions
No. of division in the Celsius scale = 100 – 0 = 100 divisions
Hence, 120 divisions on Y scale = 100 divisions on Celsius scale
So 1 division of Y scale = 100/120 = 5/6 division on Celsius scale
Hence, Temperature in Celsius C = (K – Minimum Temp) * 5/6
C = (127 -10) * 5/6 = 117 * 5/6 = 97.5 C
As the result is needed in Kelvin, we need to add 273 to 97.5 C. Hence, 370.5 Kelvin is the required answer.
