How does this affect the pressure inside the bottle?
what is the role of pressure in the set up?
1.If one increased the amount of liquid inside the bottle whilst removing gas of the same volume as liquid added, the pressure inside the bottle would remain almost constant (but decrease slightly, because gases exert more pressure on containers than liquids).
2.The hot water increases the temperature
of a soda drink inside the bottle. As the
temperature increases, more gas is
accumulated inside the bottle. This
cause the fiz zing sound.
hope its helps^^
