I think most people focus on marriage in their 20s. A lot of women would like to get married in their early to mid 20s. I think men lean towards marriage in their mid 20s to late 20s. It's a popular decade to get married, because you don't want to be too old when you begin a family.

Phase changes, such as melting or freezing, are not associated with a change in temperature. Instead, the energy associated with phase changes is used to break or form intermolecular forces between molecules.

This is to prepare you to do the work. If you are not ready for this phase, the results could be disastrous.

No. Sublimation is the action of a SOLID going directly into the GAS phase WITHOUT forming a LIQUID. This is most commonly seen in Dry Ice (solid CO2). PLASMA is a special phase associated with IONIZED GAS.
A rotary phase converter is commonly used to convert a single phase electrical power source to three phases. This allows you to use three phases instead of one.
phase shift between voltage and current waveforms. the same issue occurs with capacitors, but phase shift is in other direction. problem is most commonly associated with coils/inductors because more industrial loads are inductive (e.g. motors) than capacitive.
Commonly is water H2O.
