Answer to Question #77370 in Molecular Biology for Angela

Question

If at sea level water boils at 100 degrees Celsius while methane boils at -161 degrees Celcius which of these substances has a stronger force of attraction between its particles

Answer 1

Boiling is transformation of liquid into gas, which is followed by destruction or serious weakening of bonds between molecules. A substance, which can maintain bonds to remain liquid under higher temperatures, is likely to have stronger bonds between molecules. Water boils at higher temperatures than methane, as indicated by the provided information. Therefore, water has stronger force of attraction between its particles.
