no it weighs things down .
Hot air tends to lift things, as in a hot air balloon.
Heat generally makes things lighter, as it can cause materials to expand and increase in volume. This decrease in density results in the object being lighter for the same volume. However, in some cases where thermal expansion is negligible or if the weight change is due to other factors (such as changes in moisture content), heat might not necessarily make things lighter.
Things that give off heat are called heat sources or heaters.
Which part are you asking about ... why you see it, or why it starts to fly ?No matter. Neither of those has anything to do with heat energy.The answer to the question is: "False"
No, cold things do not have heat. Heat is a form of energy that is transferred from hot objects to cold objects. Cold objects have less heat energy compared to hot objects.
Things that release heat include fire, warm-blooded animals, and some chemical reactions like combustion. Things that absorb heat include ice melting, water evaporating, and endothermic chemical reactions.
no
Helium is lighter than air, hence it will rise up in air, making things fly.
yes
How do heat engine allow planes to fly
Thrust, lift, gravity, and drag
hi
Heat flow is made by conduction, convection or radiation.
you cant make iron, its an element.
because they both make things fly
Heat, Stirring, Particle size,
In a thermal power station, heat is turned into electrical power
the vultures use the suns heat to help them fly because if they were somewere cold they wouldn't be used to the heat so they live in hot places where there used to.
