Most cars use water to cool their engines. Ethylene glycol, propylene glycol, or methanol may be added to the water, especially in harsh climates. Why are these added to the water? A) They lower the specific heat of water, allowing it to absorb more energy. B) They lower the freezing point of the water, preventing cracking due to the formation of ice. C) They render the water poisonous to keep animals from gnawing through pipes to reach the water. D) They raise the freezing point of the water, allowing it to more easily turn to ice and cool the engine.
