# 急徵熱力學高手

這是我在普化課本裡看到的一題

有哪位化學高手可以教教我

consider a sample containing 5 mol of monatomic ideal gas that is taken from

P=3 atm V=15 L

to

P=6 atm V=20 L

the external pressure is constant and equal 6 atm

謝謝

Update:

calculate H(變化量) E(變化量) w q

hint:

you first go from P=3 atm V=15 L to P=3 atm V=20 L (constant P)

calculate deltaH, deltaE, w and q

then you go from P=3 atm V=20 L to P=6 atm V=20 L (constant V)

calculate deltaH, deltaE, w and q

Hope this help.
