2016年2月18日 · This is the triple point, where the melting and boiling temperatures are the same. Raise the pressure further, and the melting temperature stays the same $^3$ while the boiling …

2016年6月7日 · We can't predict the triple point from just liquid and vapor characteristics alone. The properties of the solid phase must enter in. In the case of water, you have many phases …

2022年7月2日 · The triple point is the temperature in which the three phases ( solid, liquid, gas) can coexist but each phase will have a different density. The critical point is the boundary …

2019年6月14日 · The Establishment of ITS-90 Water Triple Point References to ±2μK, and the Assessment of 100 Water Triple Point Cells Made Between 2001 and 2006, John P. Tavener …

2015年1月30日 · Triple point of water is a single point in P-T phase diagram of water where the three phases of water coexist. For practical applications people use the triple point cells. This …

2014年10月11日 · Stack Exchange Network. Stack Exchange network consists of 183 Q&A communities including Stack Overflow, the largest, most trusted online community for …

2019年10月23日 · The triple point of water is not found at 1 atmosphere. The triple point exists at a pressure of $661$ Pa, which is a significantly lower pressure, at a temperature of $0.01$ …

2021年3月25日 · The essential condition is the compound thermal stability. If it decomposes below its melting point, it does not have a triple point. If it decomposes before properties of …

2024年4月4日 · However, the answer was actually A. I think I get the basic reason why: looking at the triple point on a phase diagram (phase diagram of ammonia shown below), the large …

Thus, simply boiling and freezing points can't be taken as the fixed point in standard thermometers, instead, triple point is used which has a fixed value for a substance. Eg:triple …
