10 points! will mark brainiest! in a heat engine if 1,000 j of heat enters the system and the piston does 500 j of work, what is the final internal energy of the system if the initial energy was 2,000 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 you so much!

As we know that from first law of thermodynamics we have

here we know that

Q = heat given to the system

W = work done by the system

= change in internal energy of the system

now we will have

Q = 1000 J

Work done by the piston = 500 J

so work done by system of gas = -(work done by piston)

now from above equation we have

now we know that

So final internal energy of the gas is 3500 J while initial internal energy is given as 2000 J
