Sagot :
Heat transfer (in j) occurs from a system Q = - 156 J.
Briefly:-
We use thermodynamics principles in this situation. There are already obtained relationships for intense properties like internal energy (U), heat transfer (Q), and work (W) that were based on differential equations. The formula is
ΔU = Q + W
But since these factors depend on their signs, we must remember to take them into account. Van Ness, Smith, and Abbott assert that declining has a negative sign convention. If work is being done ON the system, the sign is positive; however, if work is being done BY the system, the sign is negative. in this instance,
ΔU = - 200 J\sW = - 44 J
In that case, Q can be found.
-200 J = Q - 44 J
heat transfer (in j) occurs from a system Q = - 156 J.
