4 . Read
the text "How a Balloon Flies" and find answers to the questions
given
above.
A balloon flies because the widely separated molecules
of a thin gas such as hydrogen or helium, or of the heated air that expands
inside the bag, are less dense and thus lighter than those of the air
outside the bag. In attempting to rise or escape from its confinement, the buoyant
lightweight gas or heated air
lifts the balloon along with it.
Normally, when something soars skyward, it does so by
virtue of its aerodynamic design. Like an airplane, it is lifted by the
effect of outside forces, usually wind, upon its surface. It does not soar
because it is lighter than the surrounding
atmosphere. Even a feature in the breeze is an aerodynamic form. It flies solely by the force of air currents
playing upon it. If the breeze stops, the feather slowly floats to
earth.
On the
other hand, a balloon's buoyancy is static, not dependent on a dynamic force such as wind or motor. A balloon
rises because it is filled with gas or heated air that is thinner in density
and thus lighter in weight than the surrounding atmosphere.
Because of this static, or self-sustaining lift, a
balloon is sometimes called an aerostat, and the science of ballooning, aerostation.
Balloonists also may be called aeronauts, from the Greek words aero (of the
air) and nautes (sailor).
