At the carnival, a baby was given a helium balloon whose pressure equaled the atmospheric pressure at the carnival
which was 102.7 kPa. However, the baby wasn't paying
attention and the balloon floated away into the troposphere
where the atmospheric pressure is 97.8 kPa. What is the
positive difference between the pressure in the balloon and
the pressure of the troposphere in atm?
