Question

amount of heat exchange when 1 mole ideal gas is adiabatically expanded against 2 atom constant external pressure from 2L to 12L , is​

Answer 1

Given:

1 mole ideal gas is adiabatically expanded against 2 atom constant external pressure from 2L to 12L.

To find:

Amount of heat exchanged ?

Calculation:

First of all, what is an adiabatic process?

• An adiabatic process is a thermodynamics process in which there is no exchange of heat between the system and the surroundings.

• It can be associated with compression or expansion of gases.

Now, as per the definition of adiabatic process, it's clear that the amount of heat exchanged between the system and the surroundings will be zero.

$\boxed{ \bf \therefore \: \Delta H = 0 \: joule}$
