प्रश्न

A constant-volume thermometer registers a pressure of 1.500 × 104 Pa at the triple point of water and a pressure of 2.050 × 10Pa at the normal boiling point. What is the temperature at the normal boiling point?

थोडक्यात उत्तर

उत्तर

Given:
Pressure registered by a constant-volume thermometer at the triple point, Ptr = 1.500 × 10 Pa
Pressure registered by the thermometer at the normal boiling point, P = 2.050 × 104 Pa
We know that for a constant-volume gas thermometer, temperature (T) at the normal boiling point is given as:

T`=P/P_(tr) × 273.16 K`

`=> T = (2.050 × 10^4)/1.500 × 10 ^ 4 × 273.16 K`

⇒ T = 373.31 K

Therefore, the temperature at the normal point (T) is 373.31 K.
