the answer is D because if an equal amount of heat is absorbed by the water in the containers, both water temperatures will increase, but Container B's will increase more.
When heat is absorbed by a substance, the substance's temperature increases. The amount that the temperature increases depends on the volume of the substance—the greater the volume, the less the temperature increases.
The water in Containers A and B has the same temperature, but Container A's water has a greater volume. If an equal amount of heat is added to both containers, Container A's water temperature will not increase as much as Container B's.
C: One plate is going underneath the other plate and sinking into the soft rock below.
Explanation:
Where plates are moving towards each other they are said to converging, and are called convergent margins.
The lithosphere is broken into series of slabs called plates. The plates moves on the weak and relatively soft asthenosphere below.
Plates have different motion. At some places, they move apart and they are said to be divergent.
When plates moves towards each other, they are convergent. At a convergent margin, a plate collides with another thereby causing the denser plate usually the oceanic plate to subduct into the asthenosphere. In some other cases, the plates can collide and build upward.

Answer:
.0027 M
Explanation:
We must calculate the threshold concentration of PO3−4 using Ksp and the given concentration of Ca2+:
Ca3(PO4)2(s)⇌3Ca2+(aq)+2PO3−4(aq)
Ksp=8.6×10−19=[Ca2+]3[PO3−4]2=(4.9×10−5M)3[PO3−4]2
[PO3−4]=0.0027 M
