Final answer:
Portable LPG containers have specific storage capacity limits, which are governed by safety regulations, and the capacity limit provided in the question could not be verified. The pressure in an LPG can increases with temperature due to the ideal gas law, resulting in a new pressure of 391.5 kPa when heated from 24 ℃ to 50 ℃. Storing LPG above specified temperatures or incinerating it can cause unsafe pressure increases, potentially leading to explosions.
Step-by-step explanation:
The student's question regarding the storage capacity limit for portable Liquefied Petroleum Gas (LPG) is concerned with safety regulations that prevent the storage of LPG in containers exceeding a specific weight threshold. However, the exact capacity limit was not provided in the context, and this information typically depends on local jurisdiction and safety guidelines. For the purpose of this answer, I will proceed with the assumption that the question intends to ask about a common threshold, but it is important to consult local regulations for precise information.
Regarding the part of the question involving the pressure change in an LPG can: As the temperature inside a car rises, the pressure of the gas within a can also increases due to the gas's thermal expansion. This can be explained using the ideal gas law, which states that for a given mass of gas at constant volume, the pressure of the gas is directly proportional to its absolute temperature (Kelvin).
To calculate the new pressure when the gas is heated from 24 ℃ to 50 ℃, we first convert these temperatures to Kelvin by adding 273.15. Therefore, 24 ℃ becomes 297.15 K and 50 ℃ becomes 323.15 K. Using the formula P2 = (T2/T1) * P1, where P1 is the initial pressure and T1 and T2 are the initial and final temperatures in Kelvin respectively, we can find the new pressure P2.
Substituting the given values: P2 = (323.15 K/297.15 K) * 360 kPa, we find that P2 approximately equals 391.5 kPa. This is the new pressure inside the LPG can at 50 ℃.
Storing LPG at high temperatures or incinerating it can lead to dangerous pressure increases within the container, potentially causing it to burst or explode, which is why the warning to store it below 120 ℉ (48.8 ℃) and not to incinerate is critical for safety.
