# A student measures the pressure at the bottom of a vertical column of liquid to be \( P_{total} \). If the atmospheric pressure \( P_{atm} \) doubles, what happens to the gauge pressure at the bottom of that same column?

A student measures the pressure at the bottom of a vertical column of liquid to be \( P_{total} \). If the atmospheric pressure \( P_{atm} \) doubles, what happens to the gauge pressure at the bottom of that same column?

- **A.** The gauge pressure doubles to \( 2 \) times its original value.
- **B.** The gauge pressure becomes \( 0 \).
- **C.** The gauge pressure decreases by \( \frac{1}{2} \).
- **D.** The gauge pressure remains the same.
