Balloon is too roasting to be hot. Balloon is so much more blazing
Hot air balloons use hot air because hot air rises above cold air. The air inside the balloon is heated above the temperature of the air outside the balloon. The warmer air trapped inside the balloon then causes the balloon to float above the outside colder air.
air is heavier than balloon, air rises
The volume of air increases on its heating hence the balloon rises on heating
-- Inflate the balloon with some substance that is less dense than air. OR -- Inflate the balloon with air, then heat it after it is sealed.
It rises because when thermal engery is in the balloon it makes an expansion that makes the balloon fly
Yes.
By increasing the temperature or decreasing pressure.
The solvent molecules bump into the solid more often.
Increasing the temperature the rate of evaporation increase.
destroy it
You deflate it, thus increasing the relative thickness of the rubber.
The rustin of iron can be treated as any other chemical reaction. Increasing temperature increases the rate of reaction. Hence increasing temperature can increase the rate at which iron rusts.
the temperature acted as a catalyst and excited the atoms in the solvent to make it so that they were able to pick up the valence electrons that created the bonds in the copper sulfate faster
The warmer the temperature, the faster the particles move.
By increasing the volume of the fire and the addition of salt.
use bigger wheels and use less friction on the ground make it weigh less
substance dissolve faster in a solvent? A catalyst can make a substance dissolve faster in a solvent. Increase temperature.
