In a heat engine if 1000 j of heat enters the system and the piston does 500j of work, what is the final internal energy of the system if the inital energy was 2000 j 1.write the equation 2.list out your known variables 3. plug the numbers into the equations 4.solve 5.write your solution statement that includes initial energy and final energy added.

Step-by-step explanation:

To solve this problem, we must use the first law of thermodynamics that says that the net heat absorbed by a system is equal to the sum of the work done plus the change of internal energy.

* = final internal energy of the system

* = initial internal energy of the system

* = Work done by the system

* = Heat added to the system

Then:

The final internal energy of the system is 2500 J. This means that by adding 1000j of heat to the system the internal energy increased by 500J

I think that it is 5

Step-by-step explanation:

There are 2 boys and 3 girls.3+2=5

Please tell me if I'm right.
