Vedclass · Answer

(C) The formula for the $r.m.s.$ velocity of a gas is given by $v_{rms} = \sqrt{\frac{3P}{ho}}$.Rearranging the formula to solve for pressure $P$,we get $P = \frac{ho v_{rms}^2}{3}$.Substituting the given values: $P = \frac{8.99 	imes 10^{-2} 	imes (1840)^2}{3}$.$P = \frac{8.99 	imes 10^{-2} 	imes 3385600}{3}$.$P = \frac{304365.44}{3} \approx 101455.15 \ N/m^2$.Rounding to the appropriate significant figures,$P \approx 1.01 	imes 10^5 \ N/m^2$.

If the $r.m.s.$ velocity of a gas is $v_{rms} = 1840 \ m/s$ and its density is $\rho = 8.99 \times 10^{-2} \ kg/m^3$,what is the pressure of the gas?
