A slow chemical reaction takes place in a fluid at the constant pressure of 0.1 MPa. The fluid is surrounded by a perfect heat insulator during the reaction which begins at state 1 and ends at state 2. The insulation is then removed and 105 kJ of heat flow to the surroundings as the fluid goes to state 3. The following data are observed for the fluid at states 1, 2 and 3.

State	v (m3)	t (C)
1	0.003	20
2	0.3	370
3	0.06	20

For the fluid system, calculate E₂and E₃, if E₁= 0
