The melting point of ethane and methane is almost the same.
Ethane - mp = -183 oC
Methane - mp = -182 oC
However, the boiling point of ethane is higher at -88.6 oC compared to methane at -162 oC.
Generally, the larger the molecule the higher the boiling point. This trend can be seen in the hydrocarbon series.
Methane (molar mass, Mr = 16) bp = -162 oC
Ethane (Mr = 30) bp = -88.6 oC
Propane (Mr = 44) bp = -42.2 oC
Butane (58) bp = -0.5 oC
Pentane (72) bp = 36.3 oC
and so on.
The trend is that boiling points increase as size of molecule increases. The intermolecular bonds are stronger as the larger molecules can form temporary electrostatic interaction areas. These intermolecular forces are called van der Waal forces or dispersion forces.
What else can I help you with?
What type of the following types of molecules would have the lowest melting point?
Molecules with the lowest melting points are typically small, nonpolar molecules. These include gases like noble gases (e.g., helium, neon) or simple hydrocarbons (e.g., methane, ethane) that exhibit weak van der Waals forces. The minimal intermolecular forces in these substances result in lower melting points compared to larger or polar molecules with stronger interactions.
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.
Which has a lower melting point HFor HBr?
HBr has a lower melting point of -86.8 degrees C. HF has a melting point of -83 degrees C.
Is the melting point of bromine higher or lower than the melting point of chlorine?
The melting point of bromine is -7,2 0C. The melting point of chlorine is -101,5 0C.
What point does it become a liquid?
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.
Which compound, out of the following options, has the highest boiling point: methane, ethane, propane, or butane?
Out of methane, ethane, propane, and butane, butane has the highest boiling point.

How do you calculate melting point of methane?
The melting point of methane is -182.5 degrees Celsius or -296.5 degrees Fahrenheit. This value is experimentally determined by observing the temperature at which methane transitions from a solid to a liquid state.
Is the melting point of bromine higher or lower than the melting point of chlorine?
The melting point of bromine is -7,2 0C. The melting point of chlorine is -101,5 0C.
What is the Melting point methane gas?
Methane gas melts at −184°C for more info refer the chemistry dictionary.
Lower the melting point of wax?
To lower the melting point of wax, you can consider adding a small amount of mineral oil or vegetable oil to the wax before melting it. This will decrease the overall melting temperature of the wax. Alternatively, you can mix the wax with a lower melting point wax to create a blend with a reduced melting point.
