Heat Quiz Take our heat quiz and learn some new and interesting information about energy transfer, boiling points and what happens to water at freezing temperatures. Enjoy the trivia questions & answers, put yourself to the test and see what you know about this fun science topic. The correct answer is C. The ability of an object to absorb heat is conductivity. When an object can retain high temperatures in a specific time it indicates that it is a good conductor. And while an object has low or does not have an ability to absorb heat, it is called an insulator. Dec 05, 2019 · What is heat ? State its S.I. unit. Answer: Heat is a form of energy which flows.
