Aballoon is filled with 3.60 L of H2 gas at STP. If the balloon is
taken into a sea where the pressure is 2.50 atm and the temperature is 10.00 °C, what is the new volume of H2 gas in liters?

the new volume is 1.49 L

Explanation:

stp is 0 degrees C and 1 atm.

you need to use the combined gas law formula and solve for v2

i converted the C to Kelvin

v2=p1(v1)(t2)/p2(t1)

v2=1atm(3.6L)(283.15K)/2.5atm(273.15K)

v2=1.49

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

the answer is 0.8m.
