What physical properties allow hot air balloons to fly?
Heat, the heat from the flames below the balloon cause the balloon to rise.
Does heat affect gravity?
no
How does lifting by heat cause air to rise?
Heat speeds up molecules, this causes the particles to rise
Does heat rise or hot air rise?
Heat is the energy of the hot air. Therefore hot air rises
What is the rise and fall of water due to gravity called?
The tides.
What physical properties allow hot air balloons to fly?
Heat, the heat from the flames below the balloon cause the balloon to rise.
Why do earth's oceans rise and fall in rise?
Because of gravity.
What is gravity and how gravity gave rise to the formation of Saturn?
what? I don't understand your question
How is gravity used in the procss of convection?
Gravity causes the less dense stuff to rise
How do you basically cool gas molecules?
First you compress the gas, upon which its temperature will rise. Allow it to radiate off the excess heat - the heat caused by the compression. Now allow it to expand again. It will now be colder than when you started. This is the principle upon which refrigerators work.
Does heat affect gravity?
no
What property of matter gives rise to the force of gravity?
Mass of an object influences the force of gravity on it.
Why does your temperature gauge rise and lower only when you have the heat on?
Why does your temperature gauge rise and lower only when you have the heat on?
How does lifting by heat cause air to rise?
Heat speeds up molecules, this causes the particles to rise
Do you use convection when you use heat?
convection is the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat
Does heat rise or hot air rise?
Heat is the energy of the hot air. Therefore hot air rises
What is the rise and fall of water due to gravity called?
The tides.
