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

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.

the answer to question 1 is -8, 28.
