A sample of gas is placed into an enclosed cylinder and fitted with a movable piston. Calculate the work (in joules) done by the
irga5000 [103]

Answer:

The work is -6,497.54 J

Explanation:

Work is the amount of energy transferred from one system to another by a force when a displacement occurs.

The work exchanged for a gas depends on the transformation it performs to go from the initial state to the final state.

The pressure - volume work done by a system that compresses or expands at constant pressure is given by the expression:

W= -P*ΔV

where

  • W is the work exchanged by the system with the environment. Its unit of measure in the International System is the joule (J), which is equivalent to  Pa*m³
  • P: Pressure. Its unit of measurement in the International System is the pascal (Pa).
  • ∆V: Volume variation (∆V = Vfinal - Vinitial). Its unit of measurement in the International System is cubic meter (m³)

In this case:

  • Wsystem=?
  • P= 5.63 atm=570,459.8 Pa (being 1 atm=101325 Pa)
  • ΔV=Vfinal - Vinitial= 15.61 L - 4.22 L= 11.39 L= 0.01139 m³ (being 1 L=0.001 m³)

Replacing:

W=  -570,459.8 Pa*0.01139 m³

Solving:

W=-6,497.54 J

<u><em>The work is -6,497.54 J</em></u>

IRINA_888 [86]

So wind is originally generated from the rotation of Earth spinning on it's axis which is then pushed into the high-low pressure system ( the jet streams ).

The statements that describe how the pond turned into the bog is as follows: Large water plants grew in shallow water around the edge of the pond.

<h3>What is a pond?</h3>

Pond is an inland body of standing water, either natural or man-made, that is smaller than a lake.

A bog is an area of decayed vegetation (particularly sphagnum moss) which forms a wet spongy ground too soft for walking.

This means that a pond can become a bog when existing plants in the pond decays until the land becomes soft.

Therefore, the statements that describe how the pond turned into the bog is as follows: Large water plants grew in shallow water around the edge of the pond.
