On the basis of the distribution of kinetic energies of the molecules in a liquid, explain why increasing the liquid's temperature increases the rate of evaporation. Select all that apply. O The molecules with low kinetic energy are the first to evaporate. O The molecules with high kinetic energy are the first to evaporate. O As the temperature increases, the average kinetic energy of the molecules increases. O As the temperature increases, a larger fraction of the molecules have sufficient energy to escape from the liquid. O As the temperature increases, a smaller fraction of the molecules have sufficient energy to escape from the liquid. O None of these. eTextbook and Media Save for Later Attempts: 0 of 15 used Submit Answer МacBook Air 吕0 888 F5 F6 F7 F8 F9 F10 F3 F4 F2
Four liquids are described in the table below. Use the second column of the table to explain the order of their freezing points, and the third column to explain the order of their boiling points. For example, select '1' in the second column next to the liquid with the lowest freezing point. Select '2' in the second column next to the liquid with the next higher freezing point, and so on. In the third column, select '1' next to the liquid with the lowest boiling point, '2' next to the liquid with the next higher boiling point, and so on.

4. What is the relationship between a liquid's molecular weight and the strength of intermolecular bonds (assume the liquid is only compared to other liquids that lo similar intermolecular bonds)? Use the molecular structures and weights of ethano and methanol, the types of intra- and inter- molecular bonds they make and the observations you made of ethanol and methanol in this investigation to support your answer. What is different about water's molecular structure that makes water not follow this relationship when compared to ethanol and methanol?
- Suppose a small sample of pure X is held at -236.°C and 2.0 atm. What will be the state of the sample (solid, liquid, or gas)? - Suppose the temperature is held constant at -236.°C but the pressure is decreased by 1.2 atm. What will happen to the sample (nothing, it will melt, it will freeze, it will boil, it will condense, it will sublime, or it will deposit)? - Suppose, on the other hand, the pressure is held constant at 2.0 atm but the temperature is increased by 137°C. What will happen to the sample (nothing, it will melt, it will freeze, it will boil, it will condense, it will sublime, or it will deposit)? All these are part of one question.
