An ideal monoatoinic gas is confined in a cylinder by a spring-loaded piston of area of cross-section 8 x 10−3m2. Initially, the gas is at 300 K and occupies a volume of 2.4 × 10−3m3 and the spring is in its relaxed state as shown in the figure. The gasis heated by a small electric heater until the piston moves out slowly by 0.1 m. The final temperature of the gas is________
(The force constant of the spring = 8000 Nm−1
Atmospheric pressure = 1 x 105Nm−2
The piston is massless and there is no frictionbetween the piston and cylinder)
