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.

WebFeb 13, 2024 · The effects of cold surface temperature, wet air state (temperature and humidity) and original drop size on frost dendrites growth of two neighboring separate frozen water drops of same size under natural convection conditions were investigated by quantitative measurement. It was determined that for different cold plate surface … Web12.17 Explain in terms of intermolecular forces why (a) NH3 has a higher boiling point than CH4 and (b) KCl has a higher melting point than I2. (b)KCl is an ionic compound. Ion−Ion forces are much stronger than any intermolecular forces. I2 is a nonpolar molecular substance; only weak dispersion forces are possible. biohof knaus
