The pressure of a fixed mass of an ideal gas at 27°C is 3 pa. The gas is heated at a constant volume until its pressure is 5 pa. Determine the new temperature of the gas.
- A. 100oC
- B. 227oC
- C. 273oC
- D. 500oC
Correct Answer: B. 227oC
Explanation
\(\frac{P_1}{T_1} = \frac{P_2}{T_2} = \frac{3}{300} = \frac{5}{T_2}\)
T\(_2\) = 500°C
°C = 500 - 273 = 227°
