Propellant
Gunpowderwas the first propellant used
To get an even burn through the full length of the propellant. Also, burning from the inside out keeps the propellant tube from overheating. A crack in the propellant would cause a burn to the tube wall and rupture before all the propellant is consumed.
Butane is used as a propellant in hairspray. A propellant helps the hairspray propel out of the can.
the isobitane acts as a propellant that pushes / forces the product out of the can
The burning of the propellant is what (usually) provides the thrust for the rocket to get airborne and go anywhere.
The length of time from ignition of propellant to when all propellant has been consumed.
