Question

18) Estimate pressure of air molecules at 273K, if mean square speed is 500 m²/s2 and density
of air is 6 kg/m:
2 1 x 103 Pa
c) 1 x 102 Pa
b) 2.5x 102 Pa
d) 2.7 x 103 Pa​

Answer 1

Answer:

In SI units, p is measured in pascals, V is measured in cubic metres, n is measured in moles, and T in kelvins (the Kelvin scale is a shifted Celsius scale, where 0.00 K = −273.15 °C, the lowest possible temperature).
