Why does diamond and methane have a different boiling and melting point?
Diamond and methane have different boiling and melting points because they have different molecular structures and interactions. Diamond is a covalent network solid with strong covalent bonds between carbon atoms, giving it a higher melting and boiling point. Methane, on the other hand, is a simple molecular compound with weak intermolecular forces, leading to lower melting and boiling points.
What is the freezing point of methane?
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.
Why do ammonia has higher melting and boiling point than methane?
Ammonia has hydrogen bonding between its molecules, which results in stronger intermolecular forces compared to the weaker van der Waals forces in methane. This leads to the higher melting and boiling points in ammonia than in methane.
What is the celsius melting point of ice?
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.
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 the melting point of methane is high?
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.
What is the Melting point methane gas?
Methane gas melts at −184°C for more info refer the chemistry dictionary.
Does it take more heat to melt 12 grams of CH4 or 12 grams of Hg?
It takes more heat to melt 12 grams of mercury (Hg) as it has a higher melting point compared to methane (CH4). Mercury has a melting point of -38.83 degrees Celsius, while methane melts at -182.5 degrees Celsius.
What point does it become a liquid?
A substance transitions from a solid to a liquid at its melting point, where the intermolecular forces holding its particles in a solid state weaken enough for the particles to start moving past one another.
How can you calculate melting point of subliming solid?
Impossible to calc any melting or boiling points.

What CH4 boiling point?
The boiling point of methane (CH4) is approximately -161.5 degrees Celsius (-258.7 degrees Fahrenheit) at atmospheric pressure.
How do you calculate melting points and boiling points by using enthalpy and entropy?
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.
What do you call the temperature at which a solid changes to a liquid?
This is the melting point.

What formula can be used to calculate how much additional energy is needed to reach the melting point of stainless steel taking ambient temperature into account?
You simply subtract the melting point of steel, minus the ambient temperature.
Can you calculate the melting point of an alloy?
To calculate the melting point of an alloy, one must consider the melting points of the individual elements in the alloy and their relative proportions. The melting point of an alloy is usually lower than that of its individual components due to the formation of a new phase. Phase diagrams are often used to predict the melting behavior of alloys.
