Answer:
The final temperature = 848.7 K or 575.7 °C
Explanation:
Step 1: Data given
Temperature = 25.0 °C = 298 K
Volume = 158 mL = 0.158 L
The volume increases to 450 mL = 0.450 L
The pressure is constant
Step 2: Calculate the final temperature
V1/T1 = V2/T2
⇒with V1 = the initial volume = 0.158 L
⇒with T1 = the initial temperature = 298 K
⇒with V2 = the increased volume = 0.450 L
⇒with T2 = the new temperature = TO BE DETERMINED
0.158 L / 298 K = 0.450 L / T2
T2 = 0.450 L / (0.158L/298K)
T2 = 848.7 T
The final temperature = 848.7 K or 575.7 °C
