Answer:
336.8 kilo Joules is the change in internal energy of the system.
Explanation:
The equation for first law of thermodynamics follows:
[tex]\Delta U=Q+W[/tex]
where,
Q = heat added to the system
ΔU = Change in internal energy
W = work done
We have :
Amount of heat given out by the system will be negatuive as heat relased by the system = Q
Q= [tex]-5.00\times 10^2 kJ[/tex]
Work done on the system will positive as work is done on the system:
w = [tex]2.00\times 10^2 kCal=836.8 kJ[/tex]
[tex]\Delta U=-5.00\times 10^2 kJ+836.8 kJ=336.8 kJ[/tex]
336.8 kilo Joules is the change in internal energy of the system.
