When 1 mole of an ideal monoatomic gas is compressed adiabatically the internal energy change involved is 24 cals. The temperature rise(in kelvin) is

Answer:

8.00

Solution:

$\Rightarrow Δ {U=nC}_{v} Δ T$
$\Rightarrow 24 = 1 \times \frac{3}{2} R \times Δ T \{∴ for mono atomic gas C_{v} = \frac{3}{2} R\}$
$\Rightarrow Δ T = \frac{24 \times 2}{3 \times 2} = 8 K$
