What happens if you put helium in a balloon?

So as a latex helium balloon rises, the outside air pressure diminishes, while the pressure from inside of the balloon remains the same. This causes the elastic material of the latex helium balloon to expand. As the latex expands, the helium balloon increases in volume, thereby increasing its buoyancy.

How does helium make things lighter?

So why are helium and hydrogen so much lighter than air? It’s because the hydrogen and helium atoms are lighter than a nitrogen atom. They have fewer electrons, protons and neutrons than nitrogen atoms do, and that makes them lighter (the approximate atomic weight of hydrogen is 1, helium is 4 and nitrogen is 14).

Does helium make a container lighter?

You can pressurize it in container with thick shell but then its not going to be lighter than the air (in case you think its going to produce more buoyancy ).

Why do helium balloons float in air?

It’s responding to the air around it. Helium floats because it is buoyant; its molecules are lighter than the nitrogen and oxygen molecules of our atmosphere and so they rise above it.

What happens helium?

It is made on earth via nuclear decay of uranium, and it is recovered from mines. Once it is released into the atmosphere it becomes uneconomical to recapture it, and eventually atmospheric helium will escape earth altogether because it is so light.

What happens when an alpha particle is emitted from an atom?

When a radioactive atom emits an alpha particle, the original atom’s atomic number decreases by two (because of the loss of two protons), and its mass number decreases by four (because of the loss of four nuclear particles).

What did Rutherford’s experiments demonstrate about the radioactive decay of matter?

Rutherford’s experiments demonstrated that there are three main forms of radioactive emissions. The first is called an alpha particle, which is symbolized by the Greek letter α. An alpha particle is composed of two protons and two neutrons and is the same as a helium nucleus.

What is the energy of gamma radiation emitted from radon decay?

For example, in the radioactive decay of radon-222, both alpha and gamma radiation are emitted, with the latter having an energy of 8.2 × 10−14 J per nucleus decayed: This may not seem like much energy, but if 1 mol of Rn atoms were to decay, the gamma ray energy would be 4.9 × 107 kJ!

Which of the following is an example of ionizing radiation?

X-rays and Gamma rays are examples of ionizing radiation. Some radioactive materials, emit gamma radiation during their decay. For example, in the decay of radioactive technetium-99, a gamma ray is emitted.
