College physics 1, final exam 2015 a closed 2.0l container holds 3.0 mol of an idea gas. if 200j of heat is added, and no work is done, what is the chanhe in internal enegery of the system

The change in internal energy of the system is 200 Joules

Explanation:

According to first law of thermodynamics:

=Change in internal energy

q = heat absorbed or released

w = work done or by the system

w = work done by the system=  

q = +200J   {Heat absorbed by the system is positive}

Thus the change in internal energy of the system is 200 Joules
