The leaf would be on top of the wave after two seconds just like it was positioned at 0 seconds. After 3 seconds the leaf should be positioned like it was at 1 second. The leaf is moving along with the wave.
Answer:
The final volume will be 3.39 liters
Explanation:
P1V1/T1 = P2V2/T2
P1 = 3 atm
T1 = 19( degrees celsius) + 273 = 292 K
V2 = TO BE DETERMINED
P2 =1 atm
T2 = 22( degrees celsius) + 273 = 295 k
P1V1/T1 = P2V2/T2
V2 = P1V1T2/P2T1 = (3)(1.12)(295)/(1)292) = 3.39 Liters
