Under certain circumstances, potassium ions (K+) in a cell will move across the cell membrane from the inside to the outside. The potential inside the cell is − 85.5 mV and the potential outside the cell is zero. a. What is the change in the electrical potential energy of a single potassium ion as it moves across the membrane?b. Does the potential energy of the potassium ions increase, decrease, or remain the same as the ions move from the inside to the outside?

Adiver named jacques observes a bubble of air rising from the bottom of a lake (where the absolute pressure is 3.50 atm) to the surface (where the pressure is 1.00 atm). the temperature at the bottom is 4.00 ∘c, and the temperature at the surface is 23.0 ∘c. what is the ratio of the volume of the bubble as it reaches the surface (vs) to its volume at the bottom (vb)? if jaques were to hold his breath the air in his lungs would be kept at a constant temperature. would it be safe for jacques to hold his breath while ascending from the bottom of the lake to the surface?
