Describe how the sun changes over its lifetime. when will the sun be at its brightest? when will the sun be at its hottest? in which stage of its life does the sun spend the longest time? in which stage of life will the sun undergo the most change? what kind of star will the sun be at the end of its life? . how long will the sun live for?

In a sample of oxygen gas at room temperature, the average kinetic energy of all the balls stays constant. which postulate of kinetic molecular theory best explains how this is possible? a. attractive forces between gas particles are negligible because the particles of an ideal gas are moving so quickly. b. collisions between gas particles are elastic; there is no net gain or loss of kinetic energy. c. gases consist of a large number of small particles, with a lot of space between the particles. d. gas particles are in constant, random motion, and higher kinetic energy means faster movement.
