A sealed rigid container holds gas at 27 °C and 100 kPa. The gas is heated to 327 °C. What is the new pressure?
Answer and explanation
Correct answer: C. 200 kPa
- Step 1: Convert to kelvin: K, K.
- Step 2: At constant volume , so kPa.
Answer
200 kPa.
Why not the others: 1211.1 kPa: it uses temperatures in °C instead of kelvin. 400 kPa: it adds the temperature rise to the pressure. 50 kPa: it inverts the temperature ratio.
