MCQ

Which of the following is/are true about the reversible isothermal expansion of an ideal gas?

$(a)\, \Delta U = 0$

$(b)\, q = 0$

$(c)\, \Delta T = 0$

$(d)\,q = 2.303\,nRT\,{\log _{10}}\,\left( {\frac{{{V_2}}}{{{V_1}}}} \right)$

A
$a, c$
✓
$a, c, d$
C
$b, d$
D
$a, d$

✓

Answer

Correct option: B.

$a, c, d$

b
$\Delta \mathrm{U}=0 \quad \Rightarrow \Delta \mathrm{T}=0$

and $0=\mathrm{q}+\mathrm{w}$
