Question

Mercury has mp = -38.8 °C and bp = 356.6 °C. What,if any, phase changes take place under the following condi-tions at 1.0 atm pressure? (a) The temperature of a sample is raised from -30 °C to 365 °C.

Accepted Answer

Hey everyone, we're told that the melting point and boiling point for browning is negative 7.2 degrees Celsius and 58.8 degrees Celsius, respectively, determine the phase change that happens at one atmospheric pressure when the temperature of the sample is increased from negative 6.5 degrees Celsius to 65 degrees Celsius First, I'll go ahead and pull up a phase change diagram to remind us of what's going on here. So for browning, we were told that our melting point is at negative 7.2°C, while our boiling point is at 58.8°C. Now, looking at the temperature ranges, we know that we were at negative 6.5°C and this is going to be greater than our melting point. So looking at our face change diagram, it looks like roaming is going to be a liquid at this temperature. Now looking at 65°C, this is going to be greater than our boiling point. And at this phase we can see that brewing is in its gaseous state. So the phase change is the conversion of borrowing from liquid to a gas. So this would be our reaction. Now, I hope that made sense. And let us know if you have any questions
