What is the meaning of melting point of ammonia and boiling point of ammonia?
The meaning is at what temperature does ammonia melt at and what temperature does ammonia boil at? for eg. waters melting point is 0 degrees celcius and the boiling point of water is 100 degrees celsius
What are the melting point and boiling point of Ammonium?
If you mean ammonia, the melting point of ammonia is −77.73 °C, and its boiling point is −33.34 °C. (Wikipedia)
Does ice not melt when kept in liquid ammonia?
Water ice would remain solid in liquid ammonia, because the temperature of the ammonia is well below 0 degrees Celsius, the melting point of ice. At normal atmospheric pressure, ammonia is liquid below minus 33.34 degrees C.
Which term is defined as the temperature at which a substance changes from a solid to a liquid state?
The term defined as the temperature at which a substance changes from a solid to a liquid state is called the melting point.
Why do ammonia has higher melting and boiling point than methane?
Ammonia (NH3) has hydrogen bonding intermolecular forces, whereas methane (CH4) does not. In addition, ammonia is polar, and so also has dipole-dipole forces and methane does not. Thus, it takes more energy (higher temperature) to boil and melt ammonia than it does methane.

Why is melting point of ammonia lower than water?
The melting point of a substance is based upon the polarity of the bonds that make up the substance. In water, the O-H bond has a difference in electronegativity of 1.4 (Pauling's Scale) and in ammonia, the N-H bond has a difference in electronegativity of .9. Therefore, it takes more energy to break apart the O-H bond because the polarity is so great, and this is why it has a higher melting point than ammonia.
Why does ammonia have a low melting and boiling point?
Ammonia is a compound of Hydrogen and Nitrogen(NH3). It is normally found as a stinky, lighter than air, gas.Therefore at 'room temperature' it melting point is approximately -77C, and its boiling point -33C. Its low density and atomic weight set its phase change points.
What is one major difference between titan and the early earth that would suggest that there probably isn't life on titan?
Temperature! Earth maintains a temperature near the melting point of water Titan maintains a temperature near the melting point of ammonia Ice has a positive buoyancy so it float and is in a constant state of melting. Ammonia has a negative buoyancy so it sinks and stays frozen on the bottom.
What do you call the temperature at which a solid changes to a liquid?
This is the melting point.

What is difference between melting point and drop melting point?
The melting point is the temperature at which a solid substance transitions to a liquid state. The drop melting point is a method of determining the melting point where a small amount of the substance is heated until it melts and then allowed to drop onto a solid surface to observe the melting point. Drop melting point is often used when the substance being tested has a high melting point or when observing the melting process is critical.
