Circuit A is constructed using a 6-volt battery, copper wires, and a bell. Circuit B is constructed using a 9-volt battery, string, and a bell. Circuit A produced a sound, but Circuit B did not produce a sound. Which of the following most likely explains why circuit B did not produce a sound?

• The electricity traveled in a complete path.

• There was not a switch in the circuit.

• The bell was designed to produce a small amount of sound energy.

• the string is a poor conductor of electricity.

Some students were studying different types of mixtures. They stirred together one cup of oil and one cup of water in a large glass beaker. They observed that the water settled to the bottom and the oil floated to the top. Which of the following does this investigation demonstrate?

• The oil completely dissolved in the water.

• The oil maintained it physical properties.

• The oil was more dense than the water.

• The oil melted in the water.

Four small metal cylinders were filled with boiling water and placed into different containers. Which container was the best insulator?

• Container 1

• Container 2

• Container 3

• Container 4
