Solution :
Key Idea Heat given to a system \[\gamma ,\beta ,\alpha \]is equal to the sum of increase in the internal energy \[\beta ,\gamma ,\alpha \]and the work done \[\alpha ,\beta ,\gamma \] by the system against the surrounding and 1 cat = 4.2 J. According to first law of thermodynamics \[\sigma ,-\sigma \] \[\sigma \] \[{{V}_{A}},{{V}_{B}}\] \[{{V}_{C}}\]You need to login to perform this action.
