Metal Ball And Ring Experiment

The sensor s movement trips a switch to on or off the switch may be a mercury activated switch with mercury in a glass vial that completes or breaks an electrical circuit when the vial is tilted by the coil.

Metal ball and ring experiment. For this experiment you will have to purchase a ball and ring apparatus. Ball and ring set we used the brass version heatproof mat gas bunsen burner method. Heating a metal lid on a glass bottle in order to remove the lid. Before you perform the next experiment try predicting what will hap pen when the ring is heated.

The ball once heated will not fit through the hole equipment needed. Thermal expansion ball ring. The ball passes freely through the ring when both are at the same temperature but when the ball is heated it will not pass thereby showing expansion and when it is allowed to be cooled it will again pass through the ring thereby showing contraction. Insert the ball through the ring.

Railway tracks loose phone lines contracts when weather gets colder so they re hung loosely so that phones lines don t snap egg in a bottle demonstration heating a metal lid on a glass bottle in order to remove the lid thermostat. Ball and ring experiment aim. On the end of the other is a ring through which the ball just barely fits. To show how metals expand when heated prediction.

As the ball cools you will find that it reduces in size enough to allow the ball to pass through once again. A bi metal coil contracts when cold and expands when warm. This apparatus is available in science shops as well as online. The kit includes two screwdriver like handles.

Now give the ring time to cool and once again try passing the ball through the ring. For demonstrating thermal expansion and contraction of metals when heated and cooled. To start with the ball fits through the ring. Ask the students how the ball could be made to fit through the ring.

On the end of one is a metal ball. Hold the ball and ring up to the class and show them that the ball does not pass through the ring. Perform the experiment by heating the ring and show that the ball does indeed pass through. Perform the experiment by heating the ring and show that the ball does indeed pass through.

Check to see first that the ball fits through the ring 2. Then the ball is heated and it no longer fits the is because the particles have.
