What is asked in the question i am not understanding please tell me if this question is wrong or right

2 2 Ihe internal energy of an ideal gas follows the equation U = 3.5 PV +k, where k is constant. 1 ne gas expands trom an initial volume of 0.25 dm to a final volume of 0.86 dm. If the initial pressureS 5 Nm, the change in internal energy (in Joule) is given PV1.3 = coefficient. 10 11 As per the reaction,
