For the condition of phase equilibrium the free energy is a minimum, the

system is completely stable meaning that over time the phase characteristics are constant. For metastability, the system is not at equilibrium, and there are very slight (and often imperceptible) changes of the phase characteristics with time.

They should not have either added but sometimes vendors do add an oil to keep them supple (look on the packaging for this information). Sometimes they also have sodium metastability added so that they keep their colour and fresh longer; this too should be detailed on the packaging.

Alexander V Kolobov is a Russian author known for writing science fiction novels. Some of his notable works include "Psi Factor" and "Zone of Alienation." His writing often explores themes of technology, society, and the future.

No it wont unless its God's choice

^ No. It's completely possible. The sun is going to be expanding over the next few billion years, and in that time hope that a rogue star (one floating around space with no planets) doesn't happen to come nearby. There's shitloads of things space can throw at us. There's pulsars, the vacuum metastability event, etc. Some people like our friend above think that Earth is immune, but no, we can all die right now and there won't be anyone left to care.

Flip-flop setup time refers to the minimum amount of time that the data input must be stable before the clock edge for the flip-flop to correctly latch the data. Hold time, on the other hand, refers to the minimum amount of time that the data input must be stable after the clock edge for the flip-flop to correctly store the data. In summary, setup time is the minimum time before the clock edge, while hold time is the minimum time after the clock edge for proper operation of the flip-flop.
