A gas is compressed at constant temperature from a volume of 5.68 L to a volume of 2.35 L by an external pressure of 732 torr. Calculate the work done in J

The work done in J is 324

Explanation:

To calculate the amount of work done for an isothermal process is given by the equation:

W = amount of work done = ?

P = pressure = 732 torr = 0.96 atm    (760torr =1atm)

= initial volume = 5.68 L

= final volume = 2.35  L

Putting values in above equation, we get:

To convert this into joules, we use the conversion factor:

So,

The positive sign indicates the work is done on the system

Hence, the work done for the given process is 324 J

c)as speed changes, wavelength and frequency change.

everything changes!
