1.	(b) Explain the following observations (d) The size of a weather balloon becomes larger and larger as it ascends up into larger altitude
Answer» Solution :(d) The size of a weather balloon becomes LARGER and larger as it ASCENDS up into larger ALTITUDE: According to Boyle.s law, the VOLUME of a gas is inversely proportional to the pressure at a given temperature. As the weather balloon ascends, atmospheric pressure is less , pressure of the gas tends to decrease and so volume as well as the size of the balloon INCREASES.
