Average KE per molecule
KE = (3/2)k_BT
Where: KE = kinetic energy (J), T = time period (s) / temperature (K) / tension (N), k_B = Boltzmann constant (J/K)
Solved example
Given: T = 7, k_B = 5
Find: KE_ (kinetic energy (J))
- Formula: KE = 3·T·k_B/2
- Substitute the values: KE = 3·5·7/2
- Result: KE = 52.5 J
Answer: KE_ = 52.5 J
