The action that would most likely lead to. Decrease in volume is decrease in temperature.
Scientific metod this is one of them
KE=1/2*mass*velocity^2
So u do 1/2 * 1 * 30^2
1/2 * 1 * 900
= 450kgm/s
P.s. I'm not sure if I would have to convert kg to g.
Anyways hope this helped
I believe the answer is A. Iron
I think its B but im not sure...
