Explain why methane has a low melting point

WebThe boiling point of sulfur is 444.6^ {\circ} \mathrm {C} 444.6∘C. Sulfur’s melting point is 586.1^ {\circ} \mathrm {F} 586.1∘F lower than its boiling point. Find the melting and boiling points in kelvins. Describe the relationship between the given point and the point A (8, 12) in terms of dilations. B (16, 24) WebNov 2, 2014 · The boiling point depends on the strength of the intermolecular forces between each molecule - as the length of the molecule increases, so does the force of attraction between them because there are more points to attract together. Methane has a very short chain length of only 1 carbon, so the intermolecular forces are very weak.
