A diatomic ideal gas (γ = 7/5) initially occupies a volume of 1 litre = 0.001 m3 at atmospheric pressure and 300 K. The gas is compressed adiabatically to a volume of 0.25 L. We usually write the adiabatic equation P Vγ = K. What is the numerical value of K in this case? Use standard SI (metric) units.
A) 150 Pa·m⁵
B) 300 Pa·m³
C) 450 Pa·m⁵
D) 600 Pa·m³
