It's almost always much, much easier to measure the melting point of something (or just look it up) than it is to attempt to calculate it.
The melting point of a substance is determined by heating it gradually and recording the temperature at which it changes from a solid to a liquid state. This temperature is the melting point.
Methane consists of separate CH4 molecules that can move freely and are only weakly attracted to one another. Diamond consists of a covalent network in which each carbon atom is strongly bonded to its neighbors.
Methane has a boiling point of −161 °C at a pressure of one atmosphere. For the source and more detailed information concerning this subject, click on the related links section indicated below.
That will depend on what you are considering melting.Some examples are:The melting point of methane (CH4) is -187 CelsiusThe melting point of silver is 962 CelsiusThe melting point of tin is 231.9 degrees CelsiusThe melting point of chlorine is -100.9 CelsiusThe melting point of gold is 1064.18 CelsiusThe melting point of candle wax is 37 CelsiusThe melting point of aspirin is 135 Celsiusetc.
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.
The high melting point of methane is due to its molecular structure. Methane molecules are held together by strong covalent bonds, making it difficult to break the bonds and transition from solid to liquid phase. Additionally, methane molecules are spherical and have a symmetrical shape, which contributes to the strong intermolecular forces between molecules.
Methane gas melts at −184°C for more info refer the chemistry dictionary.
At room temperature, mercury (Hg) is a liquid, and methane (CH4) is a gas. The melting point of methane is -182.5 degrees Celsius. The melting point of mercury is -39 degrees Celsius. It takes more heat to melt the mercury.
The melting point of a substance is determined by heating it gradually and recording the temperature at which it changes from a solid to a liquid state. This temperature is the melting point.
The boiling point of a substance is the point at which that substance will change between being a gas and a liquid. For example, the boiling point of water is 100oC, so water vapour will change to water at this temperature. The boiling point of Methane is -161oC, so any temperature above this, Methane will be in gas form.
Impossible to calc any melting or boiling points.
Methane consists of separate CH4 molecules that can move freely and are only weakly attracted to one another. Diamond consists of a covalent network in which each carbon atom is strongly bonded to its neighbors.
CH4's melting point is -182 C. In the context of the usual type of question about melting points, CH4 has a very low melting point because the attractions between CH4 molecules are very weak.
This is the melting point.

The melting point and boiling point of a substance are related to its enthalpy of fusion and vaporization, respectively, and its entropy of fusion and vaporization. The melting point is where the solid and liquid phases are in equilibrium, while the boiling point is where the liquid and vapor phases are in equilibrium. By analyzing the balance between enthalpy and entropy changes during phase transitions, you can predict and calculate melting and boiling points.
You simply subtract the melting point of steel, minus the ambient temperature.
