There are many chemicals found in a hot air balloon to make it rise. The main elements/chemicals are Helium and Hydrogen.
The property of certain gases that cause a hot air balloon to rise would be that warm gases rise. This creates a convection current powering the balloon.
to make the perfect water balloon, simply use a regular water balloon rather than a water balloon. regular water balloons can get as big as a human head. the down side is they don't pop easily. you can drop them on the floor and they wont pop.
Balloon twisting is the art of using balloons to make different animals and objects out of balloons. Simple objects can be made from a single balloon and multiple balloons can be twisted to make larger or more intricate designs and objects. A balloonologist is a person that practices balloon twisting, usually as a form of entertainment, rather than just a hobby.
you set paper on fire and then spit on it
Chemicals to make sick people better
taking chemicals and mixing them together.
That would be little old Helium. Hydrogen makes baloons rise even faster, but has the unfortunate disadvantage of blowing up.
no - gases are few in number - metals make up most of the periodic table
No, Dmitri Mendeleev in Russia developed the first periodic table.
The periodic table should be memorized because it will make you know the symbols without searching for them all of the time. If you are in school, it is very likely that you will be tested on the table.
There are 18 groups that make up The Periodic Table of Elements.
You dont
118 elements.
The answer is Group 17 Halogens.
Some elements in the periodic table have a nucleus that is surrounded by a cloud of electrons with a negative charge. This is one sentence using nucleus and periodic table.
No they did not.
He is the founder of the periodic table. He arranged the elements according to the atomic masses. Few changes are made in his periodic table to make the modern periodic table.
The group on the right side of the periodic table are the noble gases.
