heat
When warm air rises, bubbles of gases dissolved in liquids such as water or soda can also rise to the surface. This is because warm air is less dense than cool air and can carry lighter objects, like bubbles, upwards.
The cool air will sink and the warm air will rise.
Yes, warm air is less dense than cooler air, which causes it to rise. As air is heated, its molecules move faster and spread apart, reducing its density. This buoyancy effect allows warm air to rise through cooler, denser air, contributing to processes such as convection and weather patterns.
Mostly get hot and rise.
Add water to the boiler. You should have an automatic pressure reducing water make up valve, somewhere near the boiler. If it feeds directly into the boiler, make sure the boiler is cool when you add. Normal pressure on a cool boiler should be around 12 psi. The pressure will rise as the water is heated. You need a minimum of 1/2 psi for every foot of rise in the loop. So 12 psi in the basement will allow most systems to have a rise of appx 24 feet to the highest strip of baseboard. Remember, the pressure relief valve on the boiler lifts at 30 psi, so you need to stay well below that when the boiler is up to temperature.
it can rise because of the helium and the gases help make it rise to the sky
Hot air has less mass which make it less dense, thus allowing it to rise over a cold air mass.

To make a balloon rise in the air, one way is to fill it with a lighter-than-air gas, such as helium or hydrogen. The gas inside the balloon is less dense than the surrounding air, enabling it to float and rise. The amount of gas and the size of the balloon will determine how high it can rise.
you add air with rock Air +Rock
There are many chemicals found in a hot air balloon to make it rise. The main elements/chemicals are Helium and Hydrogen.
The 4 lifting mechanisms that make air rise are orographic lifting (when air is forced upward by a mountain or slope), frontal lifting (when warmer, less dense air is forced over cooler, denser air), convergence lifting (when air flows together and is forced to rise) and convectional lifting (when air is heated and rises due to its reduced density).
because the air becomes less dense and spreads out so becomes hotter and hot air rise so the balloon does.
A balloon needs hot air to make it rise because hot air is less dense than cold air. When the air inside the balloon is heated, it becomes lighter and causes the balloon to lift off the ground and float in the air.
You can add 'air' to make airwave. You can add 'micro' to make microwave.
Simple...hot air rises..
You leave it to make it rise, or make it double in size.
