Answer:
true
Explanation:
Rocks have different properties such as hardness and texture
Metamorphic rocks form when heat and pressure cause sedimentary or igneous rocks to recrystallize into new rock.
Soil is made up of dirt with decomposed organic material
5.0x10^1 kg is the correct answer
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.

Answer:
Heat will flow from the hotter object to the colder. The molecules in the hotter object will slow down and the molecules in the colder object will speed up. Eventually they will get to the point where they have the same temperature. This happens all the time around you.
Explanation:
Answer:
<h2>Density = 12.5 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 52.5 g
volume = 4.2 mL
Substitute the values into the above formula and solve for the density
We have
We have the final answer as
<h3>Density = 12.5 g/mL</h3>
