[題目]
1:Calculate the critical temperature of helium if the critical pressure
is 2.26atm and density is 0.069g/立方公分
2:1kg of water is boiled under a pressure of 2atm at 393k,if the volume
occupied by water and steam under given condition are respectively
0.001立方公尺 and 0.824立方公尺,calculate workdone and the increase
in internal energy.L=2.20*10J kg(-1次方)
[瓶頸]
這學期第一次接觸熱力學,這兩題是老師自己出的題目.想請問一下要用什麼方法或公式
來計算,答案都算不出來..有人算出答案那更感謝了!!
