Calculate the work done in compressing adiabatically 3kg of helium (he) to one fifth of its original volume if it is initially at 13°c. find the change in internal energy of the gas resulting from the compression. (cp/cv for monatomic gases is 1.667; gas constant for helium is 2079 k^-1 kg^-1)

Work done,

change in internal Energy ,

Explanation:

Given:

Since It is given that the process is adiabatic process it means that there is no exchange of heat between the system and surroundings

Let n be the number of moles of Helium given by

Work done in Adiabatic process

Let W be the work done

The Internal Energy change in any Process is given by

Let be the change in internal Energy

hello there!

your answer is a “generator”

a generator does not create energy but instead it transforms it.

it’s basically a motor working in reverse.
