What is the role of a switch in a circuit?

• A switch amplifies the electrical signal in a circuit.

• A switch controls the flow of electricity in a circuit by opening or closing the circuit.

• A switch stores electrical energy for later use.

• A switch converts electrical energy into mechanical energy.

What is the definition of a gas?

• A gas has a definite shape and volume.

• A gas has no definite shape or volume and expands to fill its container.

• A gas is a state of matter that is always cold.

• A gas can be compressed into a smaller volume.

What is a bar graph?

• A type of chart that uses lines to represent data trends.

• A visual representation of data using bars of different heights or lengths to compare values.

• A method of organizing data in a table format.

• A diagram that shows the relationship between two variables.

What is a line graph?

• A type of chart that displays information as a series of data points connected by straight line segments.

• A chart that uses bars to represent data values.

• A diagram that shows the relationship between two variables using dots.

• A visual representation of data using pie slices.

What is the definition of a solid?

• A solid has a definite shape and volume.

• A solid has no definite shape but a definite volume.

• A solid can flow and take the shape of its container.

• A solid is a state of matter that is always liquid.

What is a pie chart?

• A circular graph divided into slices to illustrate numerical proportions.

• A bar graph representing data with rectangular bars.

• A line graph showing trends over time.

• A scatter plot displaying the relationship between two variables.

What is a circuit?

• A circuit is a closed path that allows electric current to flow.

• A circuit is a device that stores electrical energy.

• A circuit is a type of electrical insulation material.

• A circuit is a method of measuring electrical resistance.

What is the definition of a liquid?

• A liquid has a fixed shape and volume.

• A liquid takes on the shape of its container but keeps its volume.

• A liquid can only exist at high temperatures.

• A liquid is a solid that has melted.

What is an example of a conductor?

• Plastic

• Wood

• Metal

• Glass

What is the difference between a conductor and an insulator?

• A conductor allows electricity to flow, while an insulator prevents electricity from flowing.

• A conductor prevents electricity from flowing, while an insulator allows electricity to flow.

• Both conductors and insulators allow electricity to flow equally well.

• Insulators are used to enhance the flow of electricity, while conductors are used to block it.
