< Prev
Next >

How does the specific heat of water impact its effectiveness as a coolant in automotive radiators compared to other liquids?

A

Water’s low specific heat causes rapid temperature changes, allowing for quick engine cooling

B

Water’s high specific heat allows it to absorb more heat per unit mass, making it an efficient coolant

C

Water’s specific heat decreases at higher temperatures, improving its cooling efficiency in engines

D

Water’s specific heat is irrelevant; its effectiveness is solely due to its abundance and low cost
