On the phase diagram, which section of curve represents the pressure and temperature values at which ammonia will boil? express your answer as two letters that lie on a section of the appropriate curve. on the phase diagram, which section of curve represents the pressure and temperature values at which ammonia will sublimate? express the answer as two letters that lie on a section of the appropriate curve. on the phase diagram, which section of curve represents the pressure and temperature values at which ammonia will melt? express the answer as two letters that lie on a section of the appropriate curve. one of the most important points on a phase diagram is the triple point, where gas, liquid, and solid phases all can exist at once. what are the coordinates ( ttriple, ptriple) of the triple point of ammonia in the diagram? express your answer as an ordered pair. determine the temperature to the nearest 5 kand the pressure to one significantat one atmosphere of pressure and temperatures above ? 33.3? c, ammonia exists as a gas. for transportation, ammonia is stored as a liquid under its own vapor pressure. this means that the liquid and gas phases exist simultaneously. if a container of ammonia is transported in an temperature-controlled truck that is maintained at no greater than 330 k, what maximum pressure p must the sides of the container be able to withstand?
