Water is cooled to 32K, and it appears to be on the solid phase on the phase changing diagram as the temperature is low.

Water is cooled to 32K, and it appears to be on the solid phase on the phase changing diagram as the temperature is low. We compress the ice to a temperature of 340-350K (around 30ATM on the pressure dial).a. Where is the red dot now located in the phase changing diagram? Would it be on the line between liquid and gas phases?b. What does that position on them phase change diagram say about pressure and temperature?c. What happens to the...

Water changes between solid phase (as ice) and liquid phase at 0℃. and between liquid phase and gas phase (as water vapor) at 100 ℃.

Water changes between solid phase (as ice) and liquid phase at 0℃. and between liquid phase and gas phase (as water vapor) at 100 ℃. Write a program to accept a temperature front keyboard, and display the corresponding water phase (solid, liquid or gas) under that temperature.

The activity of a free ion may be controlled by equilibrium with a solid phase that contains that ion. The activity of Al3+(aq) in equilibrium with gibbsite at pH 4 is 10-5.5. Calculate the change in concentration of Al3+(aq) if the ionic strength of the background solution (dominated by NaCl) shifts from 6 mM (6 x 10-3 M) to 60 mM (60 x 10-3 M).

How does solid solution hardening relate to a phase diagram?

In the video, you can see that when heat is applied to a solid it is converted into the liquid phase and then into the gas phase.

In the video, you can see that when heat is applied to a solid it is converted into the liquid phase and then into the gas phase. This process can be studied by plotting the graph of temperature versus the time during which heat is applied to the system. Using this information, arrange the average kinetic energy of the molecules for the following options in decreasing order. Rank from the highest to lowest. To rank items as a equivalent, overlap them.
