A cylinder of volume 3 liter has Argon gas initially at 300 K, and 1.00 atm pressure. The piston compresses the gas to a new pressure of 3.60 atm. During this compression, the temperature is maintained constant by using an appropriate heat sink. Find (a) the final volume of the gas, (b) the work done on the gas by the piston, (c) the energy transferred out by heat.(d) If the process takes 20 milliseconds, what is the power

(a) 0.833  L

(b) - 383.32J

(c) - 383.32 J

(d) 19166.2 W

Explanation:

initial volume, V = 3 L

initial temperature, T = 300 K

Initial pressure, P = 1 atm

final  pressure, P' = 3.6 atm

Temperature is constant.

(a) Let the final volume is V'.

 As the temperature is constant,

P V = P' V'

1 x 3 = 3.6 x V'

V' = 0.833 L

(b) Let the number of moles is n

The work done in isothermal process is

(c) The energy is given by the first law of thermodynamics

dQ = dU + dW

Here, dU is the zero as the temperature is constant.

So, the heat energy is

dQ = dW = - 383.32 J

(d) Time, t = 20 ms

Power is

what are the options.

explanation:

the force on the thing and the distance the force moves the thing
