Scientists digging in a cave found an unknown substance. The scientists foundthat the substance's molecules were moving around each
other. The scientistsincreased the speed of the substance's molecules
and caused a phase change. How did the scientists do this, and how did
this affect the substance?The scientists transferred energy...

A. into the substance, and the substance changed into a gas.

B. into the substance, and the substance changed into a liquid.

C. out of the substance, and the substance charged into a solid.

D. out of the substance, and the substance changed into a liquid.

Identify the electromagnets with poles that are reversed from the electromagnet shown above

What is the relationship between wind and ocean waves? question 17 options: wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves. wind moving at higher speeds will transfer energy over a larger part of the ocean water, resulting in waves with a shorter wavelength. winds moving at higher speeds with cause water to move forward at faster rates, causing larger ocean waves. winds moving at higher speeds will affect deeper water, resulting in waves that move at a faster rate. how do temperature and salinity affect deepwater currents? question 15 options: as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.

Amixture initially contains a, b, and c in the following concentrations: [a] = 0.300 m , [b] = 1.05 m , and [c] = 0.550 m . the following reaction occurs and equilibrium is established: a+2b⇌c at equilibrium, [a] = 0.140 m and [c] = 0.710 m . calculate the value of the equilibrium constant, kc.
