Vedclass · Answer

(D) Given,pressure $p = 100 \ kPa = 10^{5} \ Pa$. Initial volume $V_{1} = 1 \ m^{3}$. Final volume $V_{2} = 10 \ dm^{3} = 10 	imes 10^{-3} \ m^{3} = 0.01 \ m^{3}$. Work done on the system is given by $W = -p_{ext} \Delta V$. Since the gas is compressed,work is done on the system,so $W = p_{ext}(V_{1} - V_{2})$. $W = 10^{5} \ Pa 	imes (1 \ m^{3} - 0.01 \ m^{3}) = 10^{5} 	imes 0.99 \ J = 99,000 \ J$.

The pressure of a gas is $100 \ kPa$. If it is compressed from $1 \ m^{3}$ to $10 \ dm^{3}$,find the work done. (in $J$)
