Chapter 21, Problem 16STP

To determine

The reason of increase in the boiling point of water by antifreeze is to be explained.

Answer to Problem 16STP

Antifreeze raises the boiling point of water because to operate an engine high boiling point is required. The high boiling point ensures that the coolant remains in liquid state at all times.

Explanation of Solution

Antifreeze lowers the freezing point of a water based liquid that is a fluid such as methanol which is added to vehicle engine coolant. It is also used as heat transfer fluids to protect the systems from freezing.

When glycol antifreeze is mix with water, water turns into steam which is enough to operate the temperature of an engine.

Conclusion:

Antifreeze is an additive which lowers the freezing point of a water based liquid. The common antifreeze increases the boiling point of the liquid, allowing higher coolant temperature.
