Platinum resistance thermometer can be used upto antimony point which is ____________ °C, and is the temperature of equilibrium between solid antimony & liquid antimony at normal atmospheric pressure?
Correct answer: B. 630.74
- A. 961.93
- B. 630.74
- C. 1064.43
- D. 1261.93
Explanation
The antimony fixed point is 630.74°C, defined by equilibrium between solid and liquid antimony at standard atmospheric pressure. The other listed values correspond to different fixed points or are not the antimony point.
