4.000 x 10^3 L of propane gas is held in a tank at 25 °C. The tank has a moveable diaphragm to keep the pressure constant at 200 kPa. If the temperature falls to -5 °C on a cold winter day, what volume will the gas occupy?

1) list your givens and convert if necessary

P₁ = 200 kPa

V₁ = 4.000 × L

T₁ = 298.15 K

P₂ = 200 kPa

V₂ = ?

T₂ = 268.15 K

2) rearrange formula

3) solve

V₂ = 3597.518028 L (round as you wish)

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
