Physics - Heat & Thermo Question with Solution | TestHub

Ram is in a fix. He has returned home after a long stint at Bansal classes, but his mother has handed him an airtight container with a frictionless piston in it. The piston is such that, no air can leave the container or enter it. "Having studied so much of physics, you should be able to get this out!" Commands the mom. Ram estimates that piston area is 10 cm² and the piston weighs 100 gm. The atmospheric pressure is 1.01 × 10⁵ Pa. He knows air is inside, nothing else. The temperature is 27°C. The height of air column is 10 cm. Take R = 25/3 J/mol K.
