Far too many variables to answer ! The amount of heat required depends on the weight of the payload (basket & number people).
become a black belt and then when you are fighting sensei do a high numbered snow flake then a high number fire then another high numbered fire then a high numbered water YOU SHOULD BE ABLE TO BEAT HIM if you don't, keep trying ALSO IF YOU ARE A MEMBER YOU WILL UNLOCK THE FIRE DOJO BUY THE AMULET (AT THE FIRE DOJO) AND THEN KEEP PLAYING TO EARN YOUR FIRE SUIT...
keep distance from friends with bad influence
if we keep a pumpkin inside a balloon the balloon will not fly and will burst
There is a hot fire burning right above the basket so the hotter the air, the higher the balloon goes on!
because of the poor elasticity of the balloon
the volume of air inside the balloon increases while the pressure of balloon decreases thus balloon inflates
That may not be possible: fire - resistant, maybe. Special pyrotechnical effects crews use a gel to coat the stunt-persons arms and heads with, but even they keep plenty of fire extinguishers handy.
They keep balloon on the front self so that they would be busted. They also keep them near the front so they will not get stolen.
High pressure. A hot air balloon has a maximum altitude, where it has only just enough lift to keep it there, because there is very little difference in density between hot (near) vacuum and cold (near) vacuum.
Get yourself and your loved ones away from the fire. If you are on fire you should stop, drop, and roll or smother the flames with a blanket or towel. Another threat is the smoke and smoke inhalation. If you are in a building that is on fire, stay low to the floor and get out of there pronto.
