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

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
