Chapter 46 Cooling System

The type of heat transfer where heat is transferred from one solid to another is called:

• convection.

• conduction.

• radiation.

• thermodynamics

Heat is transferred from areas of:

• lower temperature to higher temperature.

• higher temperature to lower temperature

• both

• neither

The liquid used for the cooling system is known as:

• coolant.

• radiator fluid.

• ethylene.

• propylene.

The liquid with the best available cooling properties because of its ability to absorb large amounts of heat is:

• ethylene glycol.

• propylene glycol.

• water.

• antifreeze.

The boiling point of water in degrees Fahrenheit is:

• 100

• 200

• 175

• 212

The process of pulling chemicals apart by using electricity is known as:

• thermal breakdown.

• convection.

• conduction.

• electrolysis.

The outward force that is exerted on a rotating body is known as:

• centrifugal force.

• momentum.

• extraction.

• no answers are correct.

The normal mixture of the antifreeze and water that make up coolant is:

• 60/40

• 70/30

• 50/50

• 65/35

The passages that allow coolant to flow through the engine block and the cylinder head are known as:

• galleries.

• ports

• water jackets.

• hoses.

The component used to regulate the operating temperature of the coolant is the:

• radiator.

• thermostat.

• heater core.

• heater control valve
