Give an example of a process in which no heat is transferred to or from a system but the temperature of the system changes?

Is it possible to increase the temperature of a gas without giving it heat? OR Name the process, in which no heat is transfereed to or form a system but the temperature of the system changes.

The process in which no heat enters or leaves the system is termed as

A system undregoes a change of state during which 100kJ of heat is transferred to it and it does 50kJ of work. The system is brought back to its original state through a process during which 120kJ of heat is transferred to it. Find the work done by the system in the second process.

In which thermodynamic process the temperature of the system decreases ?

The temperature of the system decreases in the process of

When heat is added to a system at constant temperature, which of the following is possible.

In isothermal process if heat is evolved from the system then
