Which of the following statements are true regarding chemical and physical properties? Extensive properties, such as mass and volume, depend on the amount of matter being measured. Extensive properties, such as mass and volume, depend on the amount of matter being measured. Chemical properties can be measured without changing a substance’s chemical identity. Chemical properties can be measured without changing a substance’s chemical identity. Intensive properties, such as density and color, do not depend on the amount of the substance present Intensive properties, such as density and color, do not depend on the amount of the substance present Physical properties can be measured only by changing a substance’s chemical identity. Physical properties can be measured only by changing a substance’s chemical identity.

In most resting cells, the concentration of sodium ions is higher outside of cells compared with the intracellular fluid. when cells are stimulated, sodium ion channels open, and sodium diffuses from the outside of the cell to the inside of the cell. sodium ion concentrations in a resting cell are an example of and sodium ion movement in a stimulated cell is an example of in most resting cells, the concentration of sodium ions is higher outside of cells compared with the intracellular fluid. when cells are stimulated, sodium ion channels open, and sodium diffuses from the outside of the cell to the inside of the cell. sodium ion concentrations in a resting cell are an example of and sodium ion movement in a stimulated cell is an example of potential energy; kinetic energy kinetic energy; potential energy the energy of motion; stored energy chemical work; energy stored in chemical bonds
