A monatomic ideal gas with an initial pressure of 500 kPa and an initial volume of 1.80 L expands isothermally to a final volume of 5.20 L. How much work is done on the gas in this process?
A) 955 J B) 900 J C) 875 J D) 1570 J E) 1700 J
What is one idea why a relatively dense protogalactic cloud more likely to produce an elliptical galaxy than a spiral galaxy?
A) The force of gravity from the higher gas density can pull the material into a more spherical shape. B) The more frequent collisions between particles in the high-density gas randomize the particle orbits. C) The thickness of the dense cloud prevents a disk from forming. D) The higher gas density allows more rapid star formation, leaving little gas to form a disk.
