Areaction taking place in a container with a piston-cylinder assembly at constant temperature produces a gas, and the volume increases from 127 ml to 654 ml against an external pressure of 860 torr. calculate the work done in joules (j)

Work done is 60.4 Joules (J)

Explanation:

Work done 'W' is given by:

Where:

ΔV is the change in Volume.

P is the pressure.

Change in Volume=Final Volume-Initial Volume

Initial Volume= 127 mL

Final Volume= 654 mL

ΔV=654-127 (mL)

ΔV=527 mL

ΔV=0.527 L

Pressure Conversion:

1 atm=760 torr

Now,

In joule (J): (Conversion 1 atm. L=101.325 J)

Work done is 60.4 Joules (J)

60.4 J

Explanation:

The work done by the gas is given by:

where

p is the gas pressure

is the final volume of the gas

is the initial volume

We must convert all the quantities into SI units:

So the work done is

b) returns freshwater to the earth.

c) returns freshwater to the earth.c) occurs after condensation.

d) returns freshwater to the earth.c) occurs after condensation.d) roughly equal to the amount of evaporation.

pls mark as brainliest.

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.
