Which outcome occurs when ethylene glycol added to water radiator, raising boiling point?

💡 Explanation

When ethylene glycol is added to a water radiator, it raises the boiling point but reduces kinematic viscosity because it modifies the fluid's phase properties, decreasing the Reynolds number and convective heat transfer coefficient. Therefore reduces convective heat transfer results, rather than knocking, hot spots/lock, or decomposition which depend phase transition instabilities.
