A sample of nitrogen goes from 21 m3 to 14 m3 and its pressure increases from 100 kPa to 150 kPa. The final temperature is 300 K. What was the initial temperature in Kelvins?

Answer:

300 K

Explanation:

Ideal gas law:

PV = nRT

Since n and R are constants:

P₁V₁ / T₁ = P₂V₂ / T₂

(100 kPa) (21 m³) / T = (150 kPa) (14 m³) / (300 K)

T = 300 K
