• What kind of heat transfers are in a blow dryer?

    I am doing a unit 1 science project and it is asking to right about the heat transfers in a blow dryer. Can someone please tell me. A description should be wonderful. If you can right it in paragraph form that I can just copy off that will be great and I don't know how to appreciate you. I have so much homework and want to get done with this... show more
    I am doing a unit 1 science project and it is asking to right about the heat transfers in a blow dryer. Can someone please tell me. A description should be wonderful. If you can right it in paragraph form that I can just copy off that will be great and I don't know how to appreciate you. I have so much homework and want to get done with this essay. Again state the radiation, convection, and conduction in a blow dryer. How it is used inside the appliance?

  • Can you create around 100% CO2 in a bag by rebreathing it?

    If you: 1. exhale into a bag 2. close the bag (with minimum outside air contact), 3. inhale air, 4. exhale air, 5. open the bag (with minimum outside air contact), 6. inhale in the bag and repeat steps 1-6 can you create around 100% CO2 in the bag? (steps 2-4 prevent passout) Don't give an answer like: you don't exhale 100%... show more

(steps 2-4 prevent passout) Don't give an answer like: you don't exhale 100% CO2. I mean building up the CO2 every time you exhale in the bag. I forgot about the nitrogen concentration, so I change 100% CO2 to 20% CO2. Now, how would 20% kill me, if I take breaths outside of the bag in between? That would keep my oxygen level normal while the CO2 level in the bag would increase. My own CO2 level would stay normal too, because I breathe it out in the normal air too.
