Like the Kelvin scale, the ?Rankine ?scale is an absolute temperature scale: Absolute zero is zero degrees Rankine (0oR). However, the units of this scale are the same size as those of the Fahrenheit scale rather than the Celsius scale. What is the numerical value of the triple-point temperature of water on the Rankine scale?
Solution 10E STEP 1: Given that water at standard pressure freezes at 0 C ,which corresponds to 32 F and0 0 0 that it boils at 100 C .which is corresponds to 212 F . Calculate temperature difference T in degrees fahrenheit that corresponds to a temperature difference of 1 K on the kelvin scale. Above explanation given on the basis of relation between the celsius and kelvin temperature scales: A temperature increases of one kelvin corresponds to temperature increase of one degree also on celsius scale.the kelvin temperature scale and celsius temperature scale differ only in their zero. T = 1 K = 1.8 F. STEP 2: The numerical value of the triple-point temperature of water on the rankine scale is found by on the kelvin temperature scale,water freezes and coexists three phases like solid,liquid and vapour at 273.16 K at standard pressure.this temperature is known as triple point. Water triple point= 273.16 K 9/5 fahrenheit = 1 kelvin 273.16 */5 = 491.69 Rankine. 0 T triple492 R
