Asample of nitrogen is initially at a pressure of 1.7 kpa, a temperature of -10 c and a volume of 7.5 m3. then the volume is decreased to 3.8 m3. the temperature is decreased to 200 k. what is the final pressure of the nitrogen gas?

Explanation:

To solve this problem, we can use the Combined Gas Laws:

Data:

p₁ = 1.7 kPa; V₁ = 7.5 m³;  T₁ =   -10 °C

p₂ = ?;          V₂ = 3.8 m³; T₂ = 200  K

Calculations:

(a) Convert temperature to kelvins

T₁ = (-10   + 273.15) K = 263.15 K

(b) Calculate the pressure
