Assertion: In an isothermal proces, whole of heat energy supplied to the body id converted into work.
Reason: According to first law of thermodynamics `DeltaQ=DeltaU+PDeltaV`

A

If both, Assertion and Reason are true and Reason is the correct explanation of the Asserrion.

B

If both,Assertion and Reason are true but Reason is not a correct explanation of the Assertion.

C

If Assertion is true but the Reason is false.

D

If both, Assertion and Reason are false.

Text Solution

Verified by Experts

The correct Answer is:
B
Here, both assertion and reason are true but reason is not correct explanation of Assertion. In an isothermal process, `DeltaU=0`. So whole of heat supplied is used to do work against external surrounding.

Assertion In isothermal process, whole of the heat energy supplied to the body is converted into internal energy. Reason According to the first laq of thermodynamics, " " triangleQ=triangleU+triangleW

Statement-1: In isothermal process whole of the heat energy suppled to the body is converted into internal energy Statement-2: According to the first law of themodynamics. DeltaQ=DeltaU+PDeltaV

If DeltaQ and represent the heat supplied to the system and the work done on the system respectively, then the first law of thermodynamics can be written as

"It is impossible to convert total heat into work" thiis is the statement of -_____ law of thermodynamics.

Assertion : For an isothermal process in an ideal gas, the heat obsorbed by the gas is entirely used in the work done by the gas. Reason : During a process taking place in a system, the temperature remains constant then the process is isothermal.

Assertion : The efficiency of a heat engine can never be unity. Reason : Efficiency of heat engine is fundamental limitation given by first law of thermodynamics.

These questions consists of two statements each printed as Assertion and Reason. While answering these question you are required to choose any one of the following five reponses (a) If both Assertion and Reason arecorrect and Reason is the correct explanation of Asserrtion. (b) If both Assertion and Reason are correct but Reason is not the correct explanation of Assertion. (c ) If Assertion is true but Reason is false. (d) If Assertion is false but Reason is true. Assertion If work done by conservative force is negative, then potential energy associated with that force should increase. Reason This is according to the relation DeltaU=-W Here, DeltaU is change in potential energy and W is work done by conservative force.

Assertion : When current is drawn from a cell, chemical energy is converted into heat energy. Reason : This is because wire through which current flows gets heated.
