Why would a piece of metal feel colder than a piece of plastic that is the same temperature?

• Neither of these materials will conduct heat.
• Plastic is a good conductor of heat so your hand will lose heat faster while touching it.
• Metals are poor conductors of heat so your hand will not lose heat as fast while touching it.
• Metals are good conductors of heat so your hand will lose heat to a piece of metal faster.

Which of the following best explains why playground manufacturers might choose to make their slides out of plastic instead of metal?

• Plastics are good conductors of heat and so they will transfer heat quickly to people sliding down them.
• Plastics are poor conductors of heat and so they will transfer heat slowly to people sliding down them.

Why would running a jar lid under warm or hot water help you open it?

• Heating the lid will cause the molecules of the jar to expand.
• Heating the lid will cause the molecules of the lid to contract.
• Heating the lid will have no affect on lid or the jar.
