1.	If the ratio of principal specific heat capacities of a certain gas is 1:4 and its density at STP is 0.09 kgm^(-3)calculate the values of specific heat capacity at constant pressure and constant volume. [Standard atmospheric pressure =1.01 xx 10 ^(5) Nm ^(-2)
Answer» Solution :`R = P // RHO T = 1.01 XX 10 ^(5) //0.09 xx 273 = 411.7 J KG ^(-1) K ^(-1) C _(v) = r//gamma -1 = 10276.76 J kg ^(-1) K ^(-1).`
