Question

The measurement of temperature of triple point of water gives .................. °C temperature.
(A) 0
(B) -273.16
(C) 100
(D) 0.01

Answer 1

Answer:

(D) 0.01

Explanation:

As per the question,

According to thermodynamics concept, triple point is defined as the equilibrium point. At this point three phases of matter that is liquid, solid and gas coexist that is in phase equilibrium .This concept is given by James Thomson. At this point temperature is stated as 0.01°C and pressure is stated as 4.58 mm of mercury.

Hence the correct option is (D) that is 0.01°C .
