Question

1.a weather balloon functions on the principle of which gas law? a.charless law c. combined gas law b.gay-lussacs law d. boyleslaw

Explanation:

A weather balloon rises through the atmosphere, where external pressure decreases and temperature drops. As it ascends, the gas inside expands to equalize with the lower external pressure, and the volume changes in response to both pressure and temperature changes. The Combined Gas Law ($\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}$) describes the relationship between pressure, volume, and temperature of a fixed amount of gas, which matches the conditions the balloon experiences. Charles's Law only relates volume and temperature (constant pressure), Gay-Lussac's Law relates pressure and temperature (constant volume), and Boyle's Law relates pressure and volume (constant temperature) — none of these alone account for the simultaneous changes the balloon undergoes.

Answer:

C. Combined Gas Law
