Thermal Energy Pop Quiz Retake

Energy from the Sun reaches Earth by

• conduction

• convection

• radiation

• reflection

A heated metal object measures 120°C. It is dropped into a small bucket filled with water that is 10°C. Which of the following is the most likely to occur?

• Both the water and the metal will adjust to the same temperature below 10°C.

• The water and metal will adjust to different temperatures above 120°C.

• The water will remain the same temperature, but the metal will cool to 10°C.

• The water and metal will adjust to the same temperature between 10°C and 120°C.

Thermal energy transfer by conduction happens when heat moves from one object to another by

• moving across a solid barrier

• being carried in a fluid like air or water

• coming in direct physical contact with it

• traveling through empty space

You feel warmed when sitting next to a campfire. Which type of heat transfer does this represent?

• convection

• conduction

• radiation

• reflection

You decide to make dinner for your family. Nice! You put some macaroni noodles in a pot. As the water heats up, you feel the stove warming you even though you're not touching it. "Oh my goodness", you think to yourself - "it's ___(1)___!" Once the water starts boiling, you notice the noodles floating to the top, then sinking back down. "What a great example of ___(2)___!" Once they're done, you grab the handle of the pot. "OUCH" you yell. "The process of ___(3)___ got me!"

An iron heats up and then is pressed directly onto clothes to flatten out wrinkles. Which type of heat transfer does this represent?

• convection

• conduction

• radiation

• reflection

When you dive to the bottom of a pool, you notice that the water is cooler at the bottom than at the top. Which statement best describes why this would be true?

• The cooler water is more dense, so it sinks beneath the warmer water.

• The cooler water is less dense, so it sinks beneath the warmer water.

• The density of the warm and cool water are the same, but the sun reaches the top layer first.

• Warm water rises because of conduction.
