Air is held inside a non-insulated cylinder using a piston (mass M = 25 kg and area A = 100 cm²) and stoppers (of negligible area), as shown in the figure. The initial pressure P1 and temperature T1 of air inside the cylinder are 200 kPa and 400° C1 respectively, The ambient pressure P∞ and temperature T∞ are 100 kPa and 27° C respectively. The temperature of the air inside the cylinder (°C) at which the piston will begin to move is ________(correct to two deeimal places).
-
- T2 = 520.03 °C
- T2 = 150.03 °C
- T2 = 146.03 °C
- T2 = 6.03 °C
- T2 = 14.03 °C
Correct Option: C
| Pin = Pamb + | = 100 + | × 10-3 | ||
| A | 100 × 10-4 |
P2 = 124.525
| = | ||
| T1 | T2 |
