Answer:
6.30 L
Explanation:
P1 = P, V1 = 4.20 L, T1 = T
P2 = P/3, V2 = ?, T2 = T/2
Where, V2 be the final volume.
Use ideal gas equation


By substituting the values, we get
V2 = 6.30 L
Your mass wouldn’t change, but your weight would. Weight depends on the force of gravity however mass does not. When you land on the moon, your mass is the same as it was on the earth but weight will drop
T=distance over speed
T=40m over 9.8ms
T=answer
