2.

Which of the following is not the triple point of water ?

 [A]. 32°R [B]. 273°K [C]. 492°R [D]. 32°F

Explanation:

No answer description available for this question.

 Prashun said: (Jul 15, 2012) For Kelvin we do not mention degree (sign).

 Lekhanandu said: (Oct 16, 2013) Triple point of water: 0 deg C. Conversion: 0 C = 0+273 = 273K. 0 C = 32 F because T(F) = 5/9*T(C)+32. T(R) = T(F) + 459.67. So the remaining option is A.

 Bala said: (Mar 25, 2014) 32 rankine = -255.372222 degrees Celsius.

 Devankur Mishra said: (Jul 15, 2014) Triple point of water is 0.01 deg c. 0 C = 273.15 K. 0.01 =273.16 K. APPROXIMATE ANSWER WILL BE 273 K.

 Md Amir Rahman said: (Jan 6, 2015) Triple point of water: At 0° C = 273 K. = 492 R. = 32 F.

 Krishna Patil said: (Aug 27, 2017) Correct answer is 32F.

 Sandesh said: (Dec 14, 2018) What is R?

 Pratiksha said: (Sep 12, 2019) R stands for Rankine. So, R = (C*1.8) + 491.67.

 Sujeet Tiwari said: (Sep 30, 2019) Answer is A.

 D_Diksha said: (Dec 3, 2019) At a triple point all three phases (i.e. solid, liquid and) coexist. Or we can define the temperature any substance at which substance withstand three phases called triple point. For water triple point is 0. So we can calculate it in K and R.
