Predict the physical state of ammonia at -50 degrees C (Mp= -77 degrees C, Bp= -33 degrees C) and normal atmospheric pressure.
(-77 mp)......(-50).......(-33 bp).....(0)
Does this help?
To predict the physical state of ammonia at a temperature of -50 degrees Celsius, we need to compare its melting point (Mp) and boiling point (Bp) with the given temperature.
The melting point of ammonia (NH3) is -77 degrees Celsius, and the boiling point is -33 degrees Celsius.
Since -50 degrees Celsius falls in between the melting and boiling points of ammonia, we can determine its physical state by considering the pressure. However, it is important to note that the freezing point and boiling point of ammonia are generally given at standard atmospheric pressure, which is around 1 atmosphere.
At normal atmospheric pressure, if the temperature of ammonia is below its boiling point but above its melting point, it will exist as a solid. Therefore, at -50 degrees Celsius and normal atmospheric pressure, ammonia is expected to be in a solid state.
Please keep in mind that this prediction assumes the given temperature and pressure conditions. Actual physical states can vary depending on other factors such as impurities, pressure variations, or presence of a solvent.
To predict the physical state of ammonia at -50 degrees Celsius and normal atmospheric pressure, we need to consider its melting point (Mp) and boiling point (Bp).
Ammonia (NH3) has a melting point of -77 degrees Celsius and a boiling point of -33 degrees Celsius at standard atmospheric pressure (1 atm).
Given that the temperature is -50 degrees Celsius, which is between the melting and boiling points, we can say that ammonia is in a gaseous state.
The reason is that at -50 degrees Celsius, ammonia is below its boiling point but above its melting point. This means that it has not reached its boiling point and remains a gas, as the temperature is not high enough for it to change state from a gas to a liquid or a solid.
Hence, at -50 degrees Celsius and normal atmospheric pressure, ammonia is in a gaseous state.
