Which of the following statements about surface tension is false? O a. In alveoli, water molecules are more strongly attracted to each other than they are to the gas molecules. O b. Surface tension occurs at any gas-liquid boundary. O c. Surface tension resists any force that tends to increase the surface area of the gas-liquid boundary. O d. Surface tension acts to increase the size of the alveoli within the lungs. O e. Molecules of a liquid are more strongly attracted to each other than they are to gas molecules. Which of the following statements about lung surfactant is false? O a. O b. Surfactant reduces the amount of work required to inflate the lung. Surfactant works by increasing the attraction of water molecules to each other O c. Surfactant is a detergent-like mixture of lipids and peptides (short chains of amino acids) that decrease surface tension.
