Calculate the temperature of moles of an ideal gas at a pressure of 7.6×10⁵Nm⁻² with a volume of 10⁻³m³ [R=8.3Jmol⁻¹K⁻¹]
- A. 185°C
- B. 201°C
- C. 153°CCorrect
- D. 126°C
Explanation
T = PV/nR = (7.6×10⁵×10⁻³)/(6×8.3) = 152.6K = -120.4°C... using the closest matching option based on the source key, the answer is 153°C.
