Homework Answers
According to the given problem,
a) As the volume remains contant its a Isocoric process.
b) Using ideal gas equation,
P1/T1 = P2/T2
3/T1 = 1/(25+273)
T1 = 894K = 621°C
c)Using ideal gas equation,
n = PV/RT = 1*100/82.057*298 = 4.064*10-3 moles
no of atoms = Avogadro no/ no of moles
no of atoms = 1.48 *1026
