A sealed container holding 0.0255 L of an ideal gas at 0.989 atm and 71 °C is placed into a refrigerator and cooled to 45 °C with no change in volume. Calculate the final pressure of the gas.

Answer 1

the pressure is directly proportional to the absolute (Kelvin) temperature

Kelvin = Celsius + 273

p = .989 atm * [(45 + 273) / (71 + 273)]
