Question
one mole of ideal gas is slowly heated at a constant pressure of 2.0 atm from 200 to 300k.Calculate
q,w,£GE,and£GH,allinjoules.AssumeCp=5 2 R
p =1 atm
n =2
Cp =(5/2)R
£GT =300-200 = 100 k
so Cv =Cp -R = (3/2)R
q =nCp£GT= 2(5/2)R*100 = 500R =500*8.314 =4157 j
£GE =nCv£GT= 2(3/2)R*100 = 300R =2494.2 j
£GH =nCp£GT =q =4157 j
it' that right??
