1) Air modeled as an ideal gas enters a well-insulated diffuser operating at steady state at 270 K with a velocity of 180 m/s an
GarryVolchara [31]

Answer:

Explanation:

Kinetic energy of a gas molecule = 3/2 k T

1/2 m v² = 3/2 k T

v² ∝ T

(v₁ / v₂)² = T₁ / T₂

( 180 / 48.4 )² = 270 / T₂

13.83  = 270 / T₂

T₂ = 19.52 K .

Exit temp = 19.52 K .

Which formula represents Charles’s law? P1V1 = P2V2 V1T1 = V2T2
Lynna [10]

Charles's law is best represent by the formula, V1T2= V2T1.

Charles's law state that for an ideal gas, at constant pressure, the absolute volume of a gas is directly proportional to the temperature.

that is

V α T

Or

V1T2= V2T1.
