Question

What is antifreeze and also give an example?

Answer 1

An antifreeze is an additive which lowers the freezing point of a water-based liquid. An antifreeze mixture is used to achieve freezing-point depression for cold environments and also achieves boiling-point elevation ("anti-boil") to allow higher coolant temperature.eg - ethylene glycol

Answer 2

Antifreeze is a liquid which is added to water to stop it freezing. It is used in car radiators in cold weather.
This can be done in one of three ways: increase the temperature, lower the pressure, or introduce chemicals (like antifreeze for a car) .
