The answer of this question is - 173 °c
Answer:
Physical properties: how soft a blanket it, how hard bread is, what color leaves are, what bleach smells like.
Chemical change: burning wood, rotting food, digestion, rusting of a nail.
Physical change: mixing salt and sugar, tearing a piece of paper, melting ice, chopping wood.
Explanation:
Physical properties are properties that are measurable.
Chemical change is when substances combine (fire and wood make burning wood) to make another substance. They aren't reversible. If you were to melt ice, you could refreeze it, you can't unburn wood.
Physical change is something that alters the form of the substance but not the chemical composition.
Hope this helps!
Answer:
Refraction is the bending of a wave when it enters a medium where its speed is different, like going from the air (gas) to a glass of water (liquid). Absorption is when light energy penetrates an object. Typically this energy is then converted to heat.
<u>Answer</u>: Conduction, convection, and radiation move energy from the Sun to Earth and throughout Earth.
Without more information about the experiment itself, I would choose the above answer as correct. All the other statements are correct, however none of them relates to the earth distribution processes on Earth. The last statement does.
