Question

An enclosed ideal gas is taken through a cycle as shown in the figure. Then

  1. Along AB, temperature decreases while along BC temperature increases    
  2. Along AB, temperature increases while along BC the temperature decreases.    
  3. Along CA work is done by the gas and the internal energy remains constant.    
  4. Along CA work is done on the gas and internal energy of the gas increases.    

The correct answer is: Along AB, temperature decreases while along BC temperature increases

A resistance coil connected to an external battery is placed inside an adiabatic cylinder fitted with a frictionless piston and containing an ideal gas. A current i flows through the coil which has a resistance R. At what speed must the piston move upward in order that the temperature of the gas remains unchanged? Neglect atmospheric pressure.
