Is balloons filled with helium a chemical change?
No, filling balloons with helium is a physical change because the helium gas is simply occupying the space within the balloon and can be released without altering the chemical composition of the helium.
Is liquid helium boiling a physical property?
Yes, liquid helium boiling is a physical property. Boiling point is a physical property that describes the temperature at which a substance changes from a liquid to a gas. In the case of helium, its boiling point is very low at -268.9 degrees Celsius.
What are chemical changes of helium?
Helium does not undergo chemical changes under normal conditions because it is a noble gas with a full outer electron shell, making it very stable. Helium can only react under extreme conditions, such as high pressure and temperature, to form compounds with highly electronegative elements.
Is it accurate to say thet helium has no properties?
Well it is partly true. Helium has physical properties like density, boiling point, conductivity etc. But it has no chemical property.
Is helium a physical property or chemical property?
Helium is a physical property because it pertains to a characteristic that can be observed without changing the substance's chemical identity. Helium is a noble gas with a low boiling point, density, and relatively low reactivity, which are all physical properties.

What is helium's melting or boiling point?
Helium's melting point is -272.2 degrees Celsius and its boiling point is -268.9 degrees Celsius.
What are the physical properties of helium?
Helium is a colourless, odourless gas with an extremely low boiling point
Helium is a gas at room temperature Is this a chemical property of helium?
No that is a physical property.
Is helium physical or chemical property?
Helium is an element a pure substance it is a chemical. It has properties eg it is a gas, it is colourless, it is odourless
Is warming up in the sun a physical or chemical change?
Warming up in the sun is a physical change. It involves an increase in temperature causing molecules to move faster and spread out, but no new substances are formed.
What is a chemical property for helium?
One chemical property of helium is its inertness, meaning it does not easily react with other elements to form compounds. Helium is also non-toxic and has a low boiling point, making it useful for applications like cooling superconducting magnets.
Is mixing vanadium and helium a chemical change?
No. They will not react. In fact helium does not react with anything.
