______________ of water makes it a widely used coolant in heat exchangers?
Correct answer: B. High specific heat
- A. Low corrosiveness
- B. High specific heat
- C. Low dirt factor
- D. Low viscosity
Explanation
Water removes substantial heat because its specific heat is high, so a relatively large amount of energy is absorbed for each degree of temperature rise. Low viscosity also helps circulation, but it is not the main thermal reason.
