Answer:
D. Surface tension.
Explanation:
Surface tension is defined as the energy required to increase the surface area of a liquid by a unit amount.
The surface tension of a liquid results from an imbalance of intermolecular attractive forces, the cohesive forces between molecules:
A molecule in a liquid experiences cohesive forces with other molecules in all directions while molecules at the surface of a liquid experiences only net inward cohesive forces.
The answer is B. The density, or more precisely, the volumetric mass density, of a substance is its mass per unit volume.
Answer:
The heart sends blood around your body. The blood provides your body with the oxygen and nutrients it needs. It also carries away waste. Your heart is sort of like a pump, or two pumps in one
Slow cooling of magma results in the formation of c. coarse-grained textured rocks. An example of a coarse grained textured rock formed in this fashion is granite. As the rate of cooling of igneous rocks increases, the size of the crystal that is formed decreases. The Bowen's reaction series shows the different rocks cooled at different rates.
