Does Antifreeze Raise Boiling Point of Water? (Explained)
Updated: Feb 2
✔ This article has been fact checked.
Antifreeze, also known as coolant, is a liquid mixture used in internal combustion engines and other heat transfer applications to lower the freezing point and raise the boiling point of water.
The most common antifreeze is a 50/50 mixture of water and ethylene glycol, although different formulations exist with varying ratios of water to antifreeze.
Yes, antifreeze raises the boiling point of water, it prevents the coolant from boiling over when the engine runs hot. The more ethylene glycol that is added, the higher the boiling point is, a 50:50 antifreeze mixture raises the boiling point to 106℃ (223℉).
In this article, we will explain how antifreeze raises the boiling point of water and if it reduces the freezing point of water.
