Question

1) < A, -25°C >
2) < C, -35°C >
3) < D, -45°C >
4) < E, -55°C >

Answer 1

Gas laws state that pressure and temperature are directly proportional. Using Gay-Lussac's law and an initial condition of 24 °C and 360 kPa, the pressure of gas in a can left at 50 °C is about 391.6 kPa.

Step-by-step explanation:

The warnings on a can that instructs to "Store only at temperatures below 120 °F (48.8 °C). Do not incinerate.

" is essential because beyond this temperature, the gas within can expand and potentially cause the can to explode due to high pressure.

This warning relates to the concept of gas laws in physics, particularly Gay-Lussac's law, which states that the pressure of a gas is directly proportional to its temperature when the volume is held constant.

Considering the provided information about the gas can initially being at 24 °C with a pressure of 360 kPa, we can calculate the new pressure after the temperature rises to 50 °C using Gay-Lussac's law.

This law can be represented by the formula P1/T1 = P2/T2, where P stands for pressure, and T stands for temperature in Kelvin.

Therefore, we should first convert both temperatures to Kelvin: 24 °C + 273 = 297 K, and 50 °C + 273 = 323 K. Applying the formula, we get (360 kPa / 297 K) = (P2 / 323 K), and solving for P2 gives us a new pressure of approximately 391.6 kPa.
