Question

consider a sealed glass bottle. if the bottle is thrown into a fire, what will happen to the bottle and why? which law is the best explanation?
if a sealed glass bottle is thrown into a fire, it will most likely shatter or explode. the most direct explanation for this is gay - lussacs law, which states that the pressure of a gas is directly proportional to its absolute temperature.
question 2
why are scuba tanks stored in the shade rather than the sun? use a gas law to explain your answer.

Explanation:

SCUBA tanks are stored in the shade to prevent overheating. According to Gay - Lussac's law ($\frac{P_1}{T_1}=\frac{P_2}{T_2}$, where $P$ is pressure and $T$ is absolute temperature), when the temperature ($T$) of the gas inside the tank increases (if exposed to the sun), the pressure ($P$) of the gas also increases. If the pressure gets too high, it can cause the tank to rupture or become dangerous. Storing in the shade keeps the temperature of the gas relatively low, maintaining a safe pressure inside the tank.

Answer:

SCUBA tanks are stored in the shade. Using Gay - Lussac's law ($\frac{P_1}{T_1}=\frac{P_2}{T_2}$), when exposed to the sun (higher $T$), gas pressure ($P$) in the tank rises. High pressure can make the tank rupture. Shade keeps $T$ low, ensuring safe $P$.
