[MNR 1998]

Options:

A) 450 K

B) 375 K

C) 225 K

D) 405 K

Show Answer

Answer:

Correct Answer: B

Solution:

$\frac{T_{2}}{T_{1}} = {(\frac{V_{1}}{V_{2}})}^{γ - 1} \Rightarrow T_{2} = 300 {(\frac{27}{8})}^{\frac{5}{3} - 1} = 300 {(\frac{27}{8})}^{\frac{2}{3}}$

$= 300 {(\frac{27}{8})}^{1 / 3}^{2} = 800 {(\frac{3}{2})}^{2} = 675 K$

$\Rightarrow Δ T = 675 - 300 = 375 K$
