A Monatomic Ideal Gas Undergoes an Isothermal Expansion at 300

question 44

Multiple Choice

A monatomic ideal gas undergoes an isothermal expansion at 300 K, as the volume increased from 0.03 m³ to 0.21 m³. The final pressure of the gas is 60 kPA. The ideal gas constant is R = 8.314 J/mol ∙ K. The change in the internal (thermal) energy of the gas is closest to

• A) 0.00 kJ.
• B) 12 kJ.
• C) 25 kJ.
• D) -12 kJ.
• E) -25 kJ.
