How does volume affect rms speed?
How does volume affect rms speed? Since the temperature is remaining constant, the average kinetic energy and the rms speed remain the same as well. The volume of the container has decreased, which means that the gas molecules have to move a shorter distance to have a collision. What is the rms speed? The root-mean-square […]

Can an elliptical galaxy evolve into a spiral can a spiral turn into an elliptical How?
Can an elliptical galaxy evolve into a spiral can a spiral turn into an elliptical How? We know this because spiral galaxies rotate quickly (on an astronomical scale), while elliptical galaxies do not. There is no way that an elliptical galaxy could spontaneously begin rotating, so there is no way an elliptical galaxy could turn […]
