What are properties of helium?
Helium has many unique properties: low boiling point, low density, low solubility, high thermal conductivity and inertness, so it is use for any application which can explioit these properties. Helium was the first gas used for filling balloons and dirigibles.
What are the uses of curium?
Curium has two main uses: as a fuel for Radioisotope Thermal Generators (RTGs) on board satellites, deep space probes, planetary surface rovers and in heart pacemakers, and as a alpha emitter for alpha particle X-Ray spectrometry, again particularly in space applications.

What are 3 uses helium?
Helium is used for medicine, scientific research, arc welding, refrigeration, gas for aircraft, coolant for nuclear reactors, cryogenic research and detecting gas leaks. It is used for its cooling properties because of its boiling point being close to absolute zero.
What are 5 interesting facts about helium?
Ten Facts about Helium
- Helium is the second most abundant element in the universe, and the second lightest element.
- It is estimated that our sun produces 700 million tons of helium per second.
- Helium has the lowest boiling point of all elements—4.2 degrees Kelvin (that -268.8 Celsius)—just 4 degrees above absolute zero.
Why is curium used in pacemakers?
The isotope of curium used in pacemakers is Cm-242, which is an alpha particle emitter. Another benefit of using Cm-242 in pacemakers is its power output. It generates roughly 2 to 3 watts of power per gram via heat energy. This is a relatively high power output compared to other alpha emitters.
Is curium used in medicine?
Curium specialises in the production and supply of radioactive tracers used in nuclear medicine. By potentially enabling accurate early diagnosis and treatment of cancer, as well as heart, brain and bone diseases, our world-class products empower our customers with effective treatment, and proven patient outcomes.
Is curium used in pacemakers?
Curium batteries are used in pacemakers, spacecraft, satellites and planetary explorers.
Why does curium glow?
Curium glows in the dark because it is a highly radioactive element. It emits so much radiation that it can cause water to boil as soon as a sample of…
What are the uses of helium 3?
Helium-3 (He3) is gas that has the potential to be used as a fuel in future nuclear fusion power plants. There is very little helium-3 available on the Earth. However, there are thought to be significant supplies on the Moon.
Why is helium used?
Because it is very unreactive, helium is used to provide an inert protective atmosphere for making fibre optics and semiconductors, and for arc welding. Helium is also used to detect leaks, such as in car air-conditioning systems, and because it diffuses quickly it is used to inflate car airbags after impact.
What is helium used for in chemistry?
Helium is also used in the production of germanium crystals and silicon crystals. Since it has the ability to diffuse through solids much faster than air, helium is used industrially for pipeline leak detection. This element is also used in gas chromatography as a carrier gas.
Is helium a solid liquid or gas at -268?
Helium (He), chemical element, Group 18 inert gas (noble gases) of the periodic table. The second lightest element (the lightest is just hydrogen), helium is a colourless, odourless and tasteless gas that is liquid at −268.9 °C. Why does helium have a low melting point?
What are heliox mixtures?
1. Heliox mixtures in respiratory treatments for asthma, bronchitis and other lung deficiencies. By combining helium and oxygen, doctors produce a heliox gas mixture (roughly 79% helium and 21% oxygen), useful for the effective treatment of respiratory ailments like asthma and emphysema. This works by lowering overall airflow resistance.
Are helium balloons a narcotic?
Some people also use helium balloons for recreational purposes, though it does not have any narcotic properties. People inhale helium from party balloons to make there voice high-pitched as helium is less dense than air and allows sound to travel faster. But it can be a harmful practice as the uncontrolled amount of helium can be fatal.
