If you meant
'What is effervescence?'
Effervesence means escaping of gas with bubbles and hissing sound like CO2 escapes from soda water or coke bottle when opened.
Whereas, Brisk effervescence is defined as the rapid or vigorous evolution of a gas in a chemical reaction. For example, when hydrochloric acid is added to sodium bicarbonate, bubbles of carbon dioxide gas are formed vigorously.
