Answer 1

answer of this question is

square of 27 is 729

27×27=729

Answer 2

Answer :-

$\tt 27^{\circ}C\:\:=\:\:300K$

Root mean square speed = $\tt\sqrt{ \dfrac{3RT}{M}}$

R = 8.314 × 10⁷ erg K⁻¹ mol⁻¹;

M = 32g mol⁻¹ ; T = 300K

Substituting the values :-

$\tt\implies\:\:\sqrt{ \dfrac{3\times 8.314 \times 10^{7} \times 300}{32}}$

$\tt\implies\:\:48356\:cm/sec$

$\tt\implies\:\:483.56\:m/sec$

Average speed = $\tt\sqrt{\dfrac{8RT}{\pi M}}= 0.9213 \times C$

$\tt\implies\:\:0.9213 \times 48356\:cm/sec$

$\tt\implies\:\:44542\:cm/sec$

$\tt\implies\:\:445.42\:m/sec$

$\tt C_{p}\::\overline{C}:\:C$

Most probable speed = $\tt\sqrt{ \dfrac{2\times R \times T}{M}}$

$\tt\implies\:\:0.8166\times C$

$\tt\implies\:\:0.8166\times 48356\:cm/sec$

$\tt\implies\:\:39483\:cm/sec$

$\implies\:\:\tt\orange{394.83\:m/sec}$
