Solution

The correct option is C $W$
$d Q = d U + W$

$∵$ At isothermal condition $d U = 0$
Hence $d Q = W$

Q. Let Q and W denote the amount of heat given to an ideal gas and the work done by it in an isothermal process.
(a) Q = 0
(b) W = 0
(c) Q ≠ W
(d) Q = W

Q. An ideal gas expands from volume

V_{1}

V_{2}

. This may be achieved by either of three processes: isobaric, isothermal and adiabatic. Let

Δ U

be the change in internal energy of the gas , Q be the quantity of heat added to the system and W be the work done by the system on the gas. Identify which of the following statements is false for

Δ U

?

Q. Assertion :An adiabatic process in which no work is performed is an example of a constant energy process. Reason: The change in enthalpy attending an isothermal change in state of an ideal gas must be equal to the change in energy.

Q. Assertion :The heat absorbed during isothermal expansion of an ideal gas gainst vacuum is zeor. Reason: In isothermal process, change in internal energy is always zero, irrespective of ideal or real gas.

Q. STATEMENT-1 : The heat absorbed during isothermal expansion of an ideal gas against vacuum is zero.
