A) 812 J
B) 346 J
C) 751 J
D) 391 J
E) 290 J

Question

Quizplus · Accepted Answer

The heat required can be calculated using the formula Q = nCpΔT, where n is the number of moles, Cp is the molar heat capacity at constant pressure for a monatomic ideal gas (Cp = 5/2 R), and ΔT is the change in temperature. Substituting the values, Q = 1.70 moles * (5/2 * 8.314 J/mol·K) * 23.0 K = 812 J.
