Question Text
Question 1 :
Assertion: It is not possible for a system unaided by an external agency to transfer heat from a body at lower temperature to another at a higher temperature.
Reason: It is not possible to violate the 2nd law of thermodynamics.
Question 3 :
A gas kept in a container, if the container is of finite conductivity, then the process
Question 4 :
Assertion: For an isothermal process in an ideal gas, the heat obsorbed by the gas is entirely used in the work done by the gas
Reason: During a process taking place in a system, if the temperature remains constant then the process is isothermal.
