Explanation:
The heat gain by the system, q=−250kJ.
The work done on the system , w=−500kJ.
The First Law of Thermodynamics state that
ΔU=q+w
=−750kJ
The heat gain by the system, q=−250kJ.
The work done on the system , w=−500kJ.
The First Law of Thermodynamics state that
ΔU=q+w
=−750kJ

For the given values
Suppose that as the original sample absorbs heat, it expand against atmoshpheric pressure and does 600kJ of work on its surrounding.
What is ΔU?
if a sample of gas absorbs 4000kJ of heat.(3400 kJ and you have to solve with right formula such as
The heat gain by the system, q=−250kJ and The work done on the system , w=−500kJ.
The First Law of Thermodynamics state that ΔU=q+w =−750kJ.
