A term limit is a legal restriction that limits the number of terms an officeholder may serve in a particular elected office. When term limits are found in presidential and semi-presidential systems they act as a method of curbing the potential for monopoly, where a leader effectively becomes "president for life". This is intended to protect a republic from becoming a de facto dictatorship. Sometimes, there is an absolute or lifetime limit on the number of terms an officeholder may serve; sometimes, the restrictions are merely on the number of consecutive terms they may serve.
The first law of thermodynamics
dU=dQ-dW
could be expanded to
dU=TdS-PdV
where
U is internal energy,
T is temperature,
S is entropy,
P is pressure, and
V is volume.
I am trying to understand the terms one by one in plain English.
So:
V is how big the container is...
