Worked Solution & Example Answer:The diagram shows a “ball and ring” apparatus - Junior Cycle Science - Question a - 2007
Step 1
the expansion of a solid on heating
Answer
To demonstrate the expansion of a solid on heating using the ball and ring apparatus, heat the ball. As the temperature rises, the material of the ball will expand. Initially, when both the ball and ring are cold, the ball passes freely through the ring. However, upon heating, the expansion of the ball will cause it to become too large to fit through the ring, thereby illustrating that solids expand when heated.
Step 2
the contraction of a solid on cooling
Answer
To show the contraction of a solid on cooling, start by heating the ball until it does not pass through the ring. After it has been heated, allow the ball to cool down. As the ball cools, it will contract and eventually become small enough to pass through the ring again. This experiment highlights that solids contract when cooled.
