Of course not! A beaker is used to mix and measure chemicals. You do not know what chemicals have been in that beaker and many are poisonous or very harmful.
There are many energy changes which take place when burning a match. First, kinetic or movement energy is used to scrape the match. Then, the chemical energy stored in the match becomes heat energy of the flame. I am not familiar with your use of the term physical energy, but if by this you mean kinetic energy then yes this would be an example of physical energy into chemical energy.
