Determine what factors make a hot air balloon or a helium balloon float Student Instructions: 1. Why does a hot air balloon float even though it is so heavy? Hot air balloons float because the buoyancy force of the hot air is more that the weight. Buoyancy occurs because the hot air has a lower

the star.The hotter the star it is blue but when it is medium temperature it takes a red color.The shells on the red supergiant can expand when going through fusion. The red supergiant has already consumed all of its supply of hydrogen.After that helium starts to form in the core.The outer shells go through nuclear fusion making them expand. Which is why the star is huge in size. And the red supergiants are one of the most known giant stars in the galaxy. The massive star is a stage before the red

Gas Laws Gases exhibit many qualities that are very different from those of liquids or solids. Gases have particles that are farther apart when compared to liquids and solids. The particles in gases move at different speeds in random directions and they are constantly moving. These particles collide with each other and with whatever container or area they are in. Gases are also very easy to compress. They expand to fill their containers and they occupy far more space than the liquids and solids

The balloons can be packed closely together or evenly spaced. The arch can be dressed up with a variety of accents such as ribbon‚ tulle‚ poly-silk leaves‚ flowers‚ or feathers. An airfilled latex balloon can be tied directly below the helium-filled balloon‚ creating the High-Low Arch‚ a variation

the sun consumes most of its core hydrogen‚ a hydrogen rich central region remains. The star once again begins to collapse under gravity‚ and internal temperature is rise again. Hydrogen burning begins in shells outside the core while the cores helium may also combined in nuclear fusion reactions to form Carbon. These new nuclear processes may cause a star like the sun to expand briefly and become a red giant‚ a star is relatively cool outer layers glow red. Eventually however nuclear fuel

Special feauture Description Uranus was the first planet to be discovered in modern history. It was actually discovered by accident in 1781 by William Herschel. Like the other gas giants‚ Uranus has a very thick cloud cover and an atmosphere made up mostly of hydrogen‚ helium‚ methane‚ and ammonia.

lifecycle. Science of Stars What is a star? A star is defined as “a gaseous mass in space that generates energy by thermonuclear reactions”. Our sun is a star and its primary composition‚ as well as that of all the other stars‚ is helium and nitrogen gas‚ a stars core is hot and dense‚ within the core‚ the temperatures’ are extremely hot this is where atoms move so quickly that they will stick to other atoms when they collide with them‚ this forms larger atoms and releases a vast
