1.	A certain quantity of air is adiabatically compressed so that its pressure increases from 1 atmosphere to 150 atmosphere. If the initial temperature of air is 27^(@)C. Calculate (i) rise in temperature and (ii) the work done of air Y= 1.4).
Answer» <P> Solution :`T _(2) = (P_(2) //P_(1)) ^((gamma -1) lgamma) xx T_(1)= (150 //1) ^((1.4 - 1) //1.4) xx 300 = 1255.63 K, W = R ( T _(1) - T _(2)) //gamm-1 = 8.3 xx (300 - 1255.6 62//0.4 ) =- 19829.1 J`
