An ideal gas at 2 7 ∘ C is compressed adiabatically to 27 8 of its original volume. If γ = 3 5 , then the rise in temperature is:

T 2 = 300 ( 8 27 ) 3 2 = 300 × 4 9 = 675 K. Rise = 375 K, or 37 5 ∘ C. B.

An ideal gas at $2 7^{\circ}$ C is compressed adiabatically to $\frac{8}{27}$ of its original volume. If $γ = \frac{5}{3}$ , then the rise in temperature is:

Options:

Answer:

Solution:

$T_{2} = 300 (\frac{27}{8})^{\frac{2}{3}} = 300 \times \frac{9}{4} = 675$ K. Rise = $375$ K, or $37 5^{\circ}$ C. B.
