Calculate the amount of heat that must be supplied to 40 gm of nitrogen to raise its temperature by 45^(@)C at constant pressure if it is at room temperature. R = 8.3 J mol ^(-1) K ^(-1).

Calculate the amount of heat that must be supplied to 40 gm of nitroge

1.	Calculate the amount of heat that must be supplied to 40 gm of nitrogen to raise its temperature by 45^(@)C at constant pressure if it is at room temperature. R = 8.3 J mol ^(-1) K ^(-1).
Answer» <P> Solution :`Delta Q = n C _(P) DT = (40 xx 10 ^(-3) //28 xx 10 ^(-3)) xx (7 R //2) xx 45 = 1867.5 J`
