375 J. Heat is transferred to the system.

Work Step by Step

Given that, ∆E= 300 J Also, w= -75 J ( The sign is taken as negative as the work is done by the system) Using the relation ∆E = q+w, We get, q = ∆E-w = 300 J -(-75 J) = 375 J. Positive sign of q indicates that the heat is transferred to the system.
