One pound of liquid water, frozen water (ice), and vaporized water (steam) are present under the same pressure. which one would have the largest volume?

a) ice
b) steam
c) liquid water
d) they would all be the same

B Steam

Explanation:

Steam would have the largest volume. Given the same mass, a gas will have the largest volume.

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current

i think it's c. i'm not sure but i think so.
