Two gases—neon and air—are compressed in a closed system from P1 to P2 using a polytropic process with n = 1.5. requires lesser work to be compressed. The gas constants for neon and air are R = 0.4119 and 0.287 kJ/kg·K, respectively.

Agroup of students were investigating the force of gravity. they began by dropping a foam ball from a height of 3 meters into a bucket of sand. the ball hit the sand in 0.306 seconds. they dropped additional balls of approximately the same diameter, but of different masses. here is the data they collected. based on this experiment and the collected data, what would their conclusion be?
