A lamp that plugs into a wall socket draws energy which flows through a thin wire in the bulb causing it to glow. What energy transformations are taking place?

• chemical → light → electrical
• mechanical → sound → light
• thermal → solar → electrical
• electrical → thermal → light

How does a switch impact energy transfer?

• The metal pieces of the switch touch and create a closed circuit that energy can flow through

• The metal pieces of the switch touch and create an open circuit that energy can flow through

• The rubber pieces of the switch touch and create a closed circuit that energy can flow through

• A switch doesn't impact energy transfer.

Particles within an object/substance being heated are moving

• quickly.

• slowly.

• not at all.

If a paper clip is placed in a circuit, will the circuit successfully work?

• Yes, because a conductor allows electricity to freely flow

• Yes, because an insulator allows electricity to freely flow

• Yes, because a conductor does not allow electricity to freely flow

• Yes, because a insulator does not allow electricity to freely flow

The man takes the hot pot off the stove with his bare hands and his hands get burned.  This is an example of 

• conduction
• convection
• radiation
