Why are dipole-dipole molecular interactions stronger than dipole-induced dipole molecular interaction?
What will be an ideal response?
Both of these molecular interactions are electrical forces of attraction. According to Coulomb's Law, the greater the charge, the stronger the force of attraction. The charges within a dipole are larger than the charges within an induced dipole, hence, dipole-dipole molecular interactions tend to be stronger.

Why is sensible heat detectable while heat that is not sensible cannot be measured?
a. A thermometer can measure the decrease in temperature but not heat capacity. b. The latent heat of fusion cannot be calculated. c. Heat that is not sensible and heat that is sensible can both be measured. d. A thermometer measures the decrease in temperature, but as liquid changes to solid, the loss of heat is not measurable.
Deserts may be classified into categories based on climate belts and an additional category based on
human misuse. Indicate whether the statement is true or false.
Evaluate the following statement, addressing what parts, if any, are right and which are wrong:
Jointing in rocks does not affect the flow of groundwater at depths greater than 10-20m because all fractures close below that depth. Jointing is important, however, to engineers interested in stability of slopes and locating structures because joints can slide or open under gravitational forces on slopes.
Which of the following would cause uplift along an ocean-continent convergent margin?
