Answer:
D. A followed by B
Explanation:
You can see at section A solid Ice at temperature 0°C gets heated up for and all the energy generated from heating up the ice is used to break the bonds which holds the ice together as a solid .
while at Section B the liquid water at 100°C changes to vapor because the heat energy applied here breaks intermolecular bonds c.
Answer:
0.000311 m³
Explanation:
The formula that connect volume, mass and density is given below
D = m/v ...................... Equation 1
Where D = Density of the gold, m = mass of the gold, v = volume of the gold.
make v the subject of the equation
v = m/D .................. Equation 2
Given: m = 6 kg,
Note the density of pure gold = 19300 kg/m².
Substitute into equation 2
v = 6/19300
v = 0.000311 m³
Hence the volume that will verify that it's a pure gold = 0.000311 m³
The correct answer that you are looking for would be B: The layers of the Earth increase in density as one moves toward the center of the Earth.
Dose this help? if so You can Thank me by Making This Answer The Brainiest.
you would have to look up the formula and know what time and how fast and how far
