Hi I need help with this question, because I find it a bit confusing, thanks! Suppose we have a steel sheet with a circular opening, and a sphere with a diameter equal to that of the circular opening diameter. If we heat the steel sheet with a match or any heater, then which of the following statements is correct? A. The circular opening enlarges and the sphere can pass through easier. B. The circular opening shrinks(gets smaller) and the sphere can not pass through it. C. Dimensions of the circular opening do not change.
