(a) The triple point of water has a unique value of 273.16 K. At particular values of volume and pressure, the triple point of water is always 273.16 K. The melting point of ice and boiling point of water do not have particular values because these points depend on pressure and temperature. (b) The absolute zero or 0 K is the other fixed point on the Kelvin absolute scale. (c) The temperature 273.16 K is the triple point of water. It is not the melting point of ice. The temperature 0°C on Celsius scale is the melting point of ice. Its corresponding value on Kelvin scale is 273.15 K. Hence, absolute temperature (Kelvin scale) T, is related to temperature t c, on Celsius scale as: t c = T – 273.15 (d) Let T F be the temperature on Fahrenheit scale and T K be the temperature on absolute scale. Both the temperatures can be related as: Let T F1 be the temperature on Fahrenheit scale and T K1 be the temperature on absolute scale. Both the temperatures can be related as: It is given that: T K1 – T K = 1 K Subtracting equation (i) from equation (ii), we get: Triple point of water = 273.16 K ?Triple point of water on absolute scale = = 491.69
