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

Assetion : The temperature of a gas does not change when it undergoes on adiabatic process Reason: During adiabatic process , heat energy is exchanged between a system and 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.

Which of the following is correct regarding adiabatic process (i) In adiabatic process, all the three variables, P, V and T changes (ii) In adiabatic process, the heat exchanged between system and surrounding is zero i.e., DeltaQ=0 (iii) Since DeltaQ=nCDeltaT , therefore for adiabatic process molar specific heat C=0 (iv) If a gas is suddenly expanded adiabatically temperature falls and if gas is adiabatically compressed, temperature rises

Assertion:- To drink chilled juicc, we use icc cubes of 0^(@)C . Reason:- During adiabatic expansion, work is done by the gas using a part of internal energy and no heat exchange takes place the system and the surrounding.

Assertion:- During adiabatic expansion of an ideal gas, temperature falls but entropy remains constant. Reason:- During adiabatic expansion, work is done by the gas using a part of internal energy and no heat exchange teakes place the system and the surrounding.

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

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

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?
