Question
One mole of a monoatomic ideal gas occupies two chambers of a cylinder partitioned by means of a movable piston. The walls of the cylinder as well as the piston are thermal insulators. Initially equal amounts of gas fill both the chambers at null. A coil is burnt in the left chamber which absorbs heat and expands, pushing the piston to the right. The gas on the right chamber is compressed until to pressure becomes null The change in internal energy of the gas in the left chamber is
The correct answer is:
For mechanical equilibrium null
null
The change in the internal energy of the gas in the left chamber
null

The figure shows two thin rods, one made of aluminum null and the other of steel null. Each rod has the same length and the same initial temperature. They are attached at one end to two separate immovable walls. Temperature of both the rods is increased by the same amount, until the gap between the rods vanishes. Where do the rods meet when the gap vanishes?
