Answer:
As we go to higher altitudes, the atmospheric pressure decreases. Thus, the pressure outside the balloon decreases. To regain equilibrium with the external pressure, the gas inside expands to decrease its pressure. Hence, the size of the balloon increases.
(ii) In summer, due to higher temperature, the average kinetic energy of the air molecules inside the typre increases, i.e., molecules start moving faster. Hence, the pressure on the walls of teh tube increases. If pressure inside is not kept low at the time of inflation, at higher temperature, teh pressure may become so high that the tyre may burst.
