Answer:
The most correct option is A
Explanation:
The correct option is A because <u>all objects emit thermal radiation when there temperature is higher than absolute zero</u> - this is based on the Stefan-Boltzmann law. Hence, when the rods in an oven heat up above absolute zero, they begin to start emitting radiation. It should noted at this point that objects do not "emit" conduction and thus all options that involved "emitting conduction" are subsequently wrong.

Answer:
The Earth absorbs most of the energy reaching its surface
Explanation:
a small fraction is reflected. In total approximately 70% of incoming radiation is absorbed by the atmosphere and the Earth's surface while around 30% is reflected back to space and does not heat the surface.
Answer:
pOH = 0.3
Explanation:
As KOH is a strong base, the molar concentration of OH⁻ is equal to the molar concentration of the solution. That means that in this case:
With that information in mind we can<u> calculate the pOH </u>by using the following formula:
