A) increases by adiabatic process
B) increases by isothermal process
C) decreases by adiabatic process
D) remains same
E) first decreases and then increases
Correct Answer: A
Solution :
This system of thermos flask system undergoes a change under the condition that no exchange of heat takes place between the system and the surroundings, then such a process is called adiabatic process. Under this condition, if any heat is produced, it does not go out from the system and the temperature of the system is increased.
