How is energy exchanged between the system and the surroundings in the form of
(i) heat (ii) work?

In………………..process, no heat is exchanged between the system and the surroundings.

Assertion : During an adiabatic process, heat energy is not exchanged between system and its surroundings. Reason : The temperature of a gas increases when it undergoes andn adiabatic expansion.

In open system, system and surroundings exchange

During a process, the internal enegry of the system increases by 240kJ while the system performed 90 kJ of work on its surroundings. How much heta was transferred between the system and the surroundings during this process. In which direction did the heat flow?

In reference of above figure, no heat exchange between the gas and the surrounding will take place if the gas is taken along -

Explain given cases related to energy transfer between the system and surrounding – energy transferred (Q) gt 0
