Why does balloon burst if you keep on blowing?
The expansion is due to the elasticity of rubber. As we keep blowing, the air pressure builds up inside the balloon, and the rubber expands to its maximum limits. If we blow again, the balloon won’t be able to expand but the air that we blows in need space still, and the balloon bursts.
What two gases are densest?
Answer: The densest gas element is either radon (monatomic), xenon (which forms Xe2 rarely), or possibly Oganesson (element 118). Oganesson may, however, be a liquid at room temperature and pressure. Under ordinary conditions, the least dense element is hydrogen, while the densest element is either osmium or iridium.
Which gas is very heavy?
Heavy Gas – Sulfur Hexafluoride. This is a gas that can lower your voice to freaky-weird levels. Chemistry and physics teachers often use a classic science demonstration to show what happens to your voice when sound travels through a gas that’s six times lighter than air.
What is the densest gas at room temperature?
It is one of the densest known gases under standard conditions….Tungsten hexafluoride.

Which elements have the highest density?
The first chemical element with the lowest density is Hydrogen and the highest density is Osmium.
Is a black hole the densest thing in the universe?
Death by black hole Black holes are expected to form when a massive star dies. After the star’s nuclear fuel is exhausted, its core collapses to the densest state of matter imaginable, a hundred times denser than an atomic nucleus. That’s so dense that protons, neutrons and electrons are no longer discrete particles.
