Thermodynamics - Result Question 24

25. If $Δ U$ and $Δ W$ represent the increase in internal energy and work done by the system respectively in a thermodynamical process, which of the following is true? [2010, 1998]

(a) $Δ U = - Δ W$ , in an adiabatic process

(b) $Δ U = Δ W$ , in an isothermal process

(d) $Δ U = - Δ W$ , in an isothermal process

Show Answer

Answer:

Correct Answer: 25. (a)

Solution:

(a) By first law of thermodynamics, $Δ Q = Δ U + Δ W$ In adiabatic process, $Δ Q = 0$

$∴ Δ U = - Δ W$

In isothermal process, $Δ U = 0$

$∴ Δ Q = Δ W$
