50. When a fixed pressure of one atmosphere is maintained, an ideal gas receives 25 J of energy in the form of heat. During this process, the gas's volume expands from 20 cm³ to 40 cm³. What is the molar specific heat of this ideal gas?
(The universal gas constant R = 8.31 J/mol·K, 1 atm = 1.01×105 Pa)
(A) 80 J/mol·K
(B) 85 J/mol·K
(C) 90 J/mol·K
(D) 95 J/mol·K
(E) 100 J/mol·K
