Yes, liquid helium is a true substance. It is the liquid form of the element helium, which is a noble gas. At very low temperatures close to absolute zero, helium gas condenses to form liquid helium, exhibiting unique physical properties and behaviors.

Which liquid boils the quickest?

Liquid helium in the helium I phase boils at about 5 K, lower than any other substance. (Liquid helium in the helium II phase does not boil, it simply evaporates. Helium is truly weird stuff at very low temperatures.)


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 substance has the lowest viscosity?

Helium gas has the lowest viscosity among substances at room temperature and pressure.


What is the word equation for liquid helium?

The word equation for liquid helium is: Helium gas → Liquid helium.


Is helium gas a pure substance or mixture?

Helium gas is a pure substance because it is made up of only one type of atom, specifically helium atoms.


True or false the state of a substance depends on the amount of thermal energy it possesses?

True. The state of a substance, such as solid, liquid, or gas, depends on the amount of thermal energy it possesses. Increasing thermal energy can change the state of a substance, such as melting a solid into a liquid or evaporating a liquid into a gas.


Is helium gas a mixture or substance?

Helium gas is a pure substance


Is helium gas substance or mixture?

Helium gas is a pure substance


True or False- The freezing point of a substance is equal to the melting point of a substance?

True. The freezing point of a substance is the temperature at which it changes from a liquid phase to a solid phase, while the melting point is the temperature at which it changes from a solid phase to a liquid phase. In equilibrium, the freezing point and melting point of a substance are the same.


Is the helium in a balloon a substance or a mixture?

The helium in a balloon is a substance because it is made up of only one type of atom, which is helium. This means that it is a pure substance and not a mixture.


Would it be true to say that solidfication is from a liquid to gas?

False. Solidification when a substance that is in a liquid changes phase to a solid.


A gas at the same temperature as it's liquid state?

The gas and liquid states of a substance at the same temperature represent the substance's equilibrium point known as the boiling point. At this point, the vapor pressure of the liquid is equal to the atmospheric pressure, causing the liquid to boil and transform into a gas.
