Ok so First of all we start with the fire. The fire gives off radiation because you can feel the heat through space. The fire also gives of conduction because you put the hotdog on the fire to cook it, and the hotdog will give off steam when it is hot causing it to give of Convection.
There is how cooking a hotdog over a fire uses all three heat transfer
Answer:
Adding or removing energy from matter causes a physical change as matter moves from one state to another. For example, adding thermal energy (heat) to liquid water causes it to become steam or vapor (a gas). And removing energy from liquid water causes it to become ice (a solid).
Explanation:
Your welcome
Hydrogen peroxide is H2O2, while water is H2O and oxygen (a diatomic gas) is O2. The (unbalanced) reaction is:
H2O2 --> H2O + O2
Notice that the H2O2 has 2 H atoms, and so does H2. This means that both must have the same coefficients, and we can adjust the coefficient of O2. Since H2O2 has 2 O atoms, and H2O has 1, we multiply O2 by 1/2:
H2O2 --> H2O + (1/2)O2
This has an equivalent number of H and O atoms on either side, but we want the coefficients to be whole numbers, so we multiply everything by 2:
2H2O2 --> 2H2O + O2
They mainly store materials for other cells to use.
Answer:
Scenario B
Explanation:
In Scenario B; Yuki reads an article in the Professional Journal of Medicine stating that ginger root can help prevent some types of cancer. The article was published in a professional journal. Manuscripts sent to professional journals for publication must pass through a peer review process in order to ascertain the reliability of the data presented.
Magazine articles may not go through a peer review process since it is not written for the consumption of a professional audience.
