Question

A system has internal energy equal to E,, 450 J of
heat is taken out of it and 600 J of work is done on
it. The final energy of the system will be -
​

Answer 1

• Initial energy=600J
• Energy taken=450J

We know

$\boxed{\sf E=Initial energy-Taken\:Energy}$

$\\ \sf\longmapsto E=600-450$

$\\ \sf\longmapsto E=150J$

Answer 2

hope it HELPS you.

have a good day
