Answer:
469.9K
Explanation:
Using Charles's law equation:
V1/T1 = V2/T2
Where;
V1 = initial volume (ml)
V2 = final volume (ml)
T1 = initial temperature (K)
T2 = final temperature (K)
Based on the information provided:
V1 = 280.0ml
V2 = 440.0 ml
T1 = 26.0°C = 26 + 273 = 299K
T2 = ?
Using V1/T1 = V2/T2
280/299 = 440/T2
0.936 = 440/T2
T2 = 440 ÷ 0.936
T2 = 469.9K
