(a) from ethanol to propanol to n-butanol the boiling points, surface tensions, and viscosities all increase. what is the reason for this increase? (b) how do you explain the fact that propanol and ethylene glycol have similar molecular weights (60 versus 62 amu), yet the viscosity of ethylene glycol is more than 10 times larger than propa- nol? (c) how do you explain the fact that water has the highest surface tension but the lowest viscosity?

good for her? ? where is the question?

i believe the answer is a

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
