Explain why methane has a low melting point
Web15 rows · Melting Point (o C) Boiling Point (o C) State at 25 o C: methane: CH 4-183-164: gas: ethane: C 2 H 6-183-89: propane: C 3 H 8-190-42: butane: C 4 H 10-138-0.5: … WebIdentically freezing water/melting ice is locked at 0°C and only the impact being in contact with colder/hotter air is how fast it melts, not the temperature of the melting substance. Admittedly this won't lock the air above an icesheet to 0°C, but it would help moderate the temperature until it finished melting.

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. WebThe boiling point of sulfur is 444.6^ {\circ} \mathrm {C} 444.6∘C.
