Explanation:
Bone age : 22,920 years
<h3>Further explanation</h3>
Given
Nt = 2.5 g C-14
No = 40 g
half-life = 5730 years
Required
time of decay
Solution
General formulas used in decay:
t = duration of decay
t 1/2 = half-life
N₀ = the number of initial radioactive atoms
Nt = the number of radioactive atoms left after decaying during T time
Input the value :
Answer:
The answer to your question is T2 = 146.52 °K
Explanation:
Data
Volume 1 = 2.85 L
Temperature 1 = 15°C
Temperature 2 = ?
Volume 2 = 1.45 L
Process
1.- Use Charles' law to solve this problem
V1/T1 = V2/T2
2.- Convert temperature to °K
T1 = 15 + 273 = 288°K
T2 = ?
3.- Substitution
2.85/288 = 1.45/T2
Solve for T2
T2 = 1.45(288)/2.85
Simplification
T2 = 417.6/2.85
Result
T2 = 146.52 °K
