Aquaporins exclude passage of hydronium ions (H30+). But recent research has revealed a role for some aquaporins in fat metabolism, in which they allow passage of glycerol, a three-carbon alcohol (see Figure 5.11), as well as H20. Since H30+ is much closer in size to water than is glycerol, what do y

A hollow aluminum cylinder 20.0 cm deep has an internal capacity of 2.000 L at 20.08C. It is completely filled with turpentine at 20.08C. The turpentine and the aluminum cylinder are then slowly warmed together to 80.08C. (a) How much turpentine overflows? (b) What is the volume of turpentine remaini
