Which statement is false? Question 23 options: A) The average kinetic energies of molecules from samples of different "ideal" gases is the same at the same temperature. B) The molecules of an ideal gas are relatively far apart.

When Anna eats an apple, the sugars in that apple are broken down into the substance called glucose. Glucose is then burned in her body for energy. One of the body parts that needs this energy is the heart, which beats due to electrical impulses.
