What happens to the boiling point of coolant in a closed cooling system?

In a closed cooling system, the boiling point of the coolant is raised above 212 Fahrenheit due to the pressurization of the system. When the system is sealed, the pressure inside increases, which in turn raises the boiling point of the coolant. This means that the coolant can absorb more heat before it transitions from a liquid to a vapor, allowing for more efficient cooling and preventing the coolant from boiling away under normal operating temperatures.

The ability of a coolants to remain liquid at higher temperatures is crucial in many marine and industrial applications, as it ensures that the system can operate effectively without experiencing the detrimental effects of vaporization or overheating. The design of closed cooling systems takes advantage of this principle to enhance performance and reliability. In contrast, options implying constant temperatures or lower boiling points do not apply to a pressurized system.
