Question

While spending the weekend in your cabin, you burn wood in your pot-bellied stove to heat a kettle of water for tea. Answer the following questions for 2 points each:

1. What type of energy does the wood have in this situation. Explain your answer.

2. What type of energy is this transformed into as the wood it burned in the stove. Explain your answer.

3. What type of heat transfer is being used to warm the kettle of water? Why does the water eventually boil?

Answer 1

1. The wood has chemical energy because it is burning.
2. It is transforming into thermal energy as the fire emits heat.
3.The heat transfer is radiation because the fire is radiating heat. It will gain heat and reach 100 degrees celsius which is the boiling point.

Answer 2

1. The wood has chemical energy.

2. This chemical energy is transformed into thermal (heat) energy as it burns.

3. When the fire burns, it heats of the kettle of water through radiation of heat.

Step-by-step explanation:

1. It has chemical energy because when burned, it undergoes a chemical reaction to transform into heat energy, the byproduct of chemical reactions.

2. The chemical energy in the wood is transformed into heat energy because it is a byproduct of chemical reactions.

3. The water eventually boils as enough chemical energy is transformed into heat energy, which heats up the kettle of water and eventually boils it.
