Answer!
if the thermal energy of the system increases by 600 jewels and 1400 j of heat were added to the system how much work did the system do

600j

800j

1,400j

2,000j

The work done by the system is 800 Joules.

Explanation:

Internal change in thermal energy of the system,= 600 Joules

Energy added to the system the system,Q = 1400 Joules

Work done by the system can be calculated by using First law of thermodynamics:'

(First law of thermodynamics)

The work done by the system is 800 Joules.
