Forms of Energy, Conductor, Insulator , Circuits

When building a house, not only must the materials be strong and supportive, but they must also prevent heat from escaping or coming in, as well as reduce sound from traveling in and out. These materials are most likely —

• fillers

• insulators

• conductors

• liquids

When people go camping, they sometimes build fires. Which of the following describes the types of energy produced by fires and how they can be helpful to campers?

 

• Light energy can be used to see at night, and thermal energy can be used for cooking and staying warm.

• Thermal energy can be used for cooking and staying warm, and electrical energy can be used to scare away wild animals.

• . Light energy can be used to cook food, and mechanical energy can be used to scare away wild animals.

• Sound energy can be used to scare away wild animals, and electrical energy can be used to power important devices.

When a lamp is plugged in and turned on —

 

• . electrical energy flows through the lamp, and the lamp gives off light energy, only.

• mechanical energy flows through the lamp, and the lamp gives off light and sound energy.

• mechanical energy flows through the lamp, and the lamp gives off electrical energy, only.

   

• electrical energy flows through the lamp, and the lamp gives off light and thermal energy.

Which of the following shows that an electric circuit was made correctly?

 

• Electricity would flow through half of the circuit.

• The temperature of the source of the circuit would go down.

• The size of the source of the circuit would get bigger.

• Electricity would flow through the whole circuit.

Mechanical Energy is

• The energy produced by a power source

• The energy that causes a change in temperature between materials

• The energy produced from vibration that you can hear

• The energy produced by a machine or moving part
