Answer:
-149.0K
Explanation:
Charles's law states that the volume of a gas is directly proportional to the absolute temperature under constant pressure.
The equation is:
V1/T1 = V2/T2
Where V1 is initial volume = 6.00L
T1 is absolute initial temperature = 25.0°C + 273 = 298K
V2 is final volume = 2.50L
T2 is our incognite
Replacing:
6.00L/298K = 2.50L/T2
T2 = 2.50L * 298K / 6.00L
T2 = 124.17K
The temperature is 124.17K - 273.15K =
-149.0K
