Transcript of Water as a coolant

Step 1: liquid coolant flows through passages in the engines. Obstacle 1 Obstacle 2 Obstacle 3 Goal Start Why is water a useful cooling agent? Analogy Step 2: The coolant picks up the heat from the engine. Heat makes its way through rubber hose to the front of the car. How does the cooling system of a car work? Step 3: As it flows through, the hot liquid is cooled by the air stream entering the engine compartment in the front of the car. (where the grill is at) Step 4: Once the fluid is cooled, it returns to the engine to absorb more heat. The water pump is what keeps the fluid moving. How does water's high specific heat affect the climate? Water is a useful cooling agent because it absorbs a lot of heat and it doesn't let the temperature change. why would a liquid of lower specific heat capacity be not as good as water to cool an automibile engine? Since water is able to store a large amount of heat, there is less in the atmosphere. Because water has a higher heat capacity than soil and rock, coastal areas will have more moderate temperatures than inland areas because of the heat capacity of the ocean.
