(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?

Two resistors r1 and r2 may be connected either in series or parallel across an ideal battery with emf ε. we desire the rate of energy dissipation of the parallel combination to be 8.75 times that of the series combination. if r1 = 105 ω, what are the (a) smaller and (b) larger of the two values of r2 that result in that dissipation rate?
