Define triple point of water. Why is it unique?
Asked by Topperlearning User | 15th Apr, 2015, 10:36: AM
It is the temperature at which the three phases of water, namely, ice, liquid water and water vapour are equally stable and coexistent. The triple point is suitable because it is unique, i.e., it occurs at one single temperature = 273.15 K and one single pressure of about 0.46 cm of the Hg column. This point is unique because any temperature or pressure higher or lower will change the phase of one or more states of water.

- If 200gm ice at -50°c and 100gm water at 20°c mixed with 10gm steam at 110°c mixed with each other then what will be the temperature of mixture. Is ice remain left, if yes then find the amount of ice,vapour or water

- Answer the following: The triple-point of water is a standard fixed point in modern thermometry. Why? What is wrong in taking the melting point of ice and the boiling point of water as standard fixed points (as was originally done in the Celsius scale)?
- A solid material is supplied with heat at constant rate. The temperature of the material is changing with the heat input as shown in the figure. Study the graph carefully and answer the following questions. (i) What do the horizontal regions AB and CD represent? (ii) If CD= 2AB, what do you infer? (iii) What does the slope DE represent? (iv) The slope of OA>the slope of BC. What does this indicate?
