The upper mantle of Earth is a very thick layer of rock inside the planet, which begins just beneath the crust (at about 10 km (6.2 mi) under the oceans and about 35 km (22 mi) under the continents) and ends at the top of the lower mantle at 670 km (420 mi). Temperatures range from approximately 200 °C (392 °F) at the upper boundary with the crust to approximately 900 °C (1,650 °F) at the boundary with the lower mantle. Upper mantle material which has come up onto the surface is made up of about 55% olivine, 35% pyroxene and 5 to 10% of calcium oxide and aluminum oxide minerals such as plagioclase, spinel, or garnet, depending upon depth.
George is lifting weights. He starts by doing biceps curls
which involves flexing his
elbows. His elbow is able to bend
because the humero-ulnar joint is a hinge
joint. Sam is doing leg presses, extending his knees as he pushes
against the weights. Meanwhile, Jane is doing "lat pulls" by pulling
downward on a weighted bar. This movement involves adduction of her arms.
Her shoulder joint is a ball-and-socket joint, allowing
a wide range of movements.
FIRST LAW OF THERMODYNAMICS *the total heat
energy applied to the system is equal to the sum of the change in
internal energy of the system and the work done <span>by the system.
</span>
SECOND LAW OF THERMODYNAMICS (entropy) *no
process in w/c the total entropy decreases is possible when all the
systems taken apart in the <span>process are considered.
BONUUUUSSS :D
</span>
<span> THIRD LAW OF THERMODYNAMICS *The entrophy of a perfect crystal of a substance at the absolute temp. is zero.
