What else can I help you with?
Is helium a gas or a solid?
Helium is a gas at room temperature and pressure. It only becomes a solid at very low temperatures close to absolute zero.
Is helium a liqiud or a solid or gas?
Helium is a gas at room temperature and pressure. It can be liquefied at very low temperatures (-269°C) and becomes a liquid at that point. Helium does not exist in a solid state under normal conditions.
Why type of matter is helium?
Helium is a chemical element and a noble gas, which is a type of matter that exists in a gaseous state at room temperature and pressure.
Why hydrogen and helium does not satisfy joule Thomson effect?
As the gs flow from high pressure to low pressur using the porus plug the temperature of the gas increases as the pressure of the gas decreases. As we know in all this process the enthalpy is constant . So, to stay it constant the internal energy increases which lead to increase in temperature of the gas. Formula h=u+pv h--- enthalpy u-- internal energy p--pressure v---volume
What form is helium?
Helium is a chemical element, and its most common form is a gas at room temperature and pressure.
What is the inversion temperature of Helium at a pressure of 330 bars?
This is a stupid question
Why do hydrogen and helium get having very low temperatures warmed up instead of cooling in joule-thomson method?
There is for every gas a point called the inversion temperature. Above this temperature, the gas exhibits a reverse Joule-Thompson effect and warms on expansion instead of cooling. The inversion temperatures for hydrogen and helium are quite low compared to those of most other gases.
Are hydrogen and helium gases?
They can be depending on the temperature and pressure. They can also be liquids and solids. At room temperature and pressure they are gases.
Is helium a gas or a solid?
Helium is a gas at room temperature and pressure. It only becomes a solid at very low temperatures close to absolute zero.
What substance is not a solid at 20C and one atmosphere of pressure?
At 20°C and one atmosphere of pressure, helium is not a solid. Helium exists as a gas at this temperature and pressure.
Is helium a liqiud or a solid or gas?
Helium is a gas at room temperature and pressure. It can be liquefied at very low temperatures (-269°C) and becomes a liquid at that point. Helium does not exist in a solid state under normal conditions.
What is the gas constant of helium and how does it affect the behavior of helium gas under different conditions?
The gas constant of helium is 8.314 J/molK. This constant determines how helium gas behaves under different conditions, such as temperature and pressure. It helps in calculating the relationship between the amount of helium gas, its temperature, and pressure.
How many grams is 1 Liter of Helium?
you need to state the temperature and pressure. The ideal gas law shows that pressure is inversely proportional to volume and temp is proportionally to volume, so volume, and thus, concentration of molecules, thus weight would be different depending on the temperature and pressure.

Will all the real gas be liquefied at high pressure?
No. It takes a combination of pressure and temperature to liquefy some gases. Hydrogen and helium were the last gases to be liquefied and that was with pressure and extremely low temperature.
