1.A gas at 250k and 15 bar has a molar volume 12 per cent
larger than that calculated from the perfect
gas law calculate (a) the compression factor under these conditions and
(b) the molar volume of the gas
2.I2 has a heat capacity Cp of 80j/mol k and a boiling point at 458k
When 1 mol of I2 358k to 458k in the liquid state at 1atm, calculate the
(a)三角形h (b)三角形s an electric current of 2.0A from a 12V supply is passed
for 1 hour through a resistance the liquid vaporized completely at 458k
and 1 atm calculate(c) Q(d) W (e)三角形U (f)三角形H (g)三角形S
the vapor at 458K and 1 atm was then heated to 558K and 2 atm
calculate (h)三角形U (i)三角形H (j)三角形S
(for the I2 vapor Cp=30+0.005T J/(mol K)
麻煩大大幫忙 這兩題真想很久還是卡關
大大解出來 一定P幣奉上 感謝
