Explain why different liquids do not reach the same height in capillary tubes of the same diameter. Please choose the best explanation. A.  Cohesive forces stronger than adhesive forces reduce the height of the liquid in the capillary tube, whereas adhesive forces stronger than cohesive forces increase the height of the liquid. B.  The height of the liquids in the capillary tubes depends on the density of the liquid. C.  Different liquids have different intermolecular forces. The stronger the intermolecular forces within the liquid, the higher the liquid rises in the capillary tube.

The pressure above a pure sample of solid Substance X at -64. °C is lowered. At what pressure will the sample sublime? Use the phase diagram of X below to find your answer. pressure (atm) solid atm 200 liquid 400 X gas temperature (K) Note: your answer must be within 0.25 atm of the exact answer to be graded correct. 600

Question 11 of 20 Which statement describes why the viscosity of maple syrup is higher than that of orange juice? O A. The molecules that make up maple syrup are negative ions, while the molecules that make up orange juice are positive ions. O B. The molecules that make up maple syrup have a harder time moving past one another because they are smaller than the molecules that make up orange juice. C. The molecules that make up maple syrup are positive ions, while the molecules that make up orange juice are negative ions. D. The molecules that make up maple syrup have a harder time moving past one another because they are larger than the molecules that make up orange juice.

Which of the following statements is INCORRECT based on intermolecular forces of attraction? A.  Pentane (C5H12) has a low viscosity due to lack of dipole-dipole interactions. B. Liquids having strong intermolecular forces have low vapor pressures. C. The viscosity increases with increasing tempeature.
