Which of the following is an engine coolant property

Explanation:

Engine Coolant:

• An engine coolant (also called an antifreeze) is a special fluid that runs through your engine to keep it within its correct operating temperature range.
• It is made from either ethylene glycol or propylene, water, some protection additives and is usually green, blue or even pink in colour.

Engine Coolant properties:

An efficient cooling system removes 30 to 35% of the heat generated in the combustion chamber.

• Coolant should remove heat at a fast rate when the engine is hot.
• Coolant should remove heat at a slow rate when the engine is started until the engine reaches its normal operating temperature.
• Coolant should not remove too much heat from the engine. Too much removal of the heat decreases the thermal efficiency of the engine.
• It should have a Low freezing point
• It should have high thermal conductivity.
• It should have high thermal stability.
• It should have a high thermal specific heat
• It should circulate freely in the coding system.
• It should prevent frequency and rust formations.
• It should be reasonably cheap.
• It should not waste by vaporization.
• It should not deposit any foreign matter in the water jackets/radiator.
