Answer:
109.7K
Step-by-step explanation:
Using Charles law equation as follows;
V1/T1 = V2/T2
Where;
V1 = initial volume (L)
V2 = final volume (L)
T1 = initial temperature (K)
T2 = final temperature (K)
According to the information provided in this question;
V1 = 0.67L
V2 = 0.21L
T1 = 350K
T2 = ?
Using the formula above;
0.67/350 = 0.21/T2
0.001914 = 0.21/T2
0.001914T2 = 0.21
T2 = 0.21/0.001914
T2 = 109.7K
