Question 757 Deck Safety

The correct answer is D) 135°F. The safety discs on carbon dioxide cylinders are set to release at 2,700 psi. Under normal circumstances, this pressure will be reached at a temperature of 135°F. This is because carbon dioxide follows the ideal gas law, where pressure is directly proportional to temperature. As the temperature increases, the pressure inside the cylinder also increases, and the safety disc is designed to release at 2,700 psi, which corresponds to a temperature of 135°F. The other answer choices are incorrect because they do not accurately reflect the temperature at which the safety disc will release. A temperature of 70°F, 100°F, or 125°F would not generate the necessary 2,700 psi pressure inside the cylinder to trigger the safety disc.
