There are is always vapor leaving a liquid and liquid condensing back into it, even if it is not boiling. That's why if you spill some water it evaporates and disappears. Boiling is when the vapor pressure of the liquid equals the atmospheric pressure.
By the way, what you see is NOT vapor--it is small water droplets in the air, water vapor is invisible.

THE SOUP IS WARMER THAN THE AMBIENT TEMPERATURE AND THE VAPOR RISING FROM IT SHOWS UP AS A CONDENSATE WHICH WE SEE LIKE IT WAS STEAM BUT IT'S MORE LIKE SEEING YOUR BREATH WHEN YOU'RE OUTSIDE ON A COLD DAY.

Because it's warmer then the air temp.... It's like condensation.
